    npm Uninstall – How to Remove a Package

    Working with packages is made easier by the Node Package Manager (NPM), which provides a variety of commands.Additionally, you may remove a package from the npm library in the same way that you would install it.To uninstall a package, you may use the npm uninstall command, which is supplied by the npm package management system.However, the method by which you remove an ordinary package or dependence is not the method by which you should uninstall a global package and a development dependent.In this post, I’ll teach you how to remove an ordinary package, a global package, and a development dependency all in the same session.

    How to Remove a Package with npm Uninstall

    To uninstall a package using the npm uninstall command, use the following syntax in the directory where the package is located: npm uninstall package-name npm uninstall package-name This tutorial will illustrate how to remove a package using the Express framework, which is based on the NodeJS programming language.In the package.json file, you can see that Express is listed as a dependent, as seen in the picture below.However, once I run npm uninstall express, you will no longer see Express mentioned as a dependent: As you can see, there is no longer an Express dependence.There is even no longer a dependence key since there is no longer a dependency.

    How to Remove a Dev Dependency with npm Uninstall

    A development dependency is a package that is only utilized during the development process.To uninstall a development dependency, you must first attach the -D or -save-dev flag to the npm uninstall command, and then enter the name of the package you want to uninstall.To accomplish this, use the npm uninstall -D package-name or npm uninstall -save-dev package-name syntax, which is the most basic.Ensure that you execute the command in the directory (folder) in which the dependent is located.For this demonstration, I will be using the Nodemon framework to explain how to remove a development dependency.Nodemon allows you to have your NodeJS application reload automatically whenever a change is detected in a file or folder while developing.

    1. As you can see in the picture below, Nodemon is listed as a development requirement for the project.
    2. I’m going to run npm uninstall –D to get rid of it.
    3. nodemon As you can see in the package.json file, there is no longer a Nodemon component.

    How to Remove a Global Package with npm Uninstall

    Unlike other packages, a global package is one that is installed worldwide on your computer, meaning that you do not have to reinstall it every time you need to use it.Remove a global package by using the -g parameter to the npm uninstall command and then specifying the package’s name in the command line argument.To do this, use the npm uninstall -g package-name command as the basis of your command.I’ll use the CORS package to demonstrate how to uninstall a global package in order to save time (Cross-origin Resource Sharing).CORS prevents browsers from implementing the Same Origin Policy (SOP), allowing you to send requests from one browser to another.In the screenshot below, you can see that the CORS package is not mentioned as a component of the package.

    1. The json file is as follows: This is due to the fact that CORS is installed globally on my system, rather than in the directory of a specific project.
    2. If you’ve installed a package globally and want to check what you’ve installed, use npm list -g.
    3. You can see that CORS is now labeled as a global package, which is a good thing.
    4. I’ll now execute npm uninstall -g cors to remove CORS from the system as a whole.
    5. When I run npm list –g, I can see that there is no longer any CORS, which indicates that the command was successful.

    Uninstall packages completely from a project — manually or automatically

    The original version of this story may be found here. Working with Node.js projects requires the installation and uninstallation of dependencies on a regular basis. Look at this article if you are just getting started with Node.js — How to install npm packages — for some pointers. Uninstalling packages may be accomplished in two ways: manually or automatically.

    Uninstalling dependencies

    If you want to uninstall a package, you must first delete it from your node modules folder (where the code is stored) and then from the package.json file (listed there as a project dependency).Similarly, if you merely delete it from the node modules folder and then run npm install, the package will be reinstalled, and if you only remove it from the package.json file, the package will still be present in the node modules directory.But don’t be concerned.The npm uninstall command will take care of both of these tasks.To eliminate dependencies, follow the steps outlined below:

    1. By searching through your package, you may find the package that you wish to remove. json
    2. Run the following command, replacing the name of the package (or multiple packages separated by spaces) with the name of the package

    Remove npm from your system Once the command has been successfully executed, the NPM CLI will uninstall the package and report information to the terminal about how many packages were successfully uninstalled. Uninstalling a package removes the given package as well as all of the packages that were utilized internally as dependents by the package.

    Check to make sure it has been removed from the package.This is dependent on the version of npm that you have installed.Since the introduction of npm version 5 (in 2017), installing or removing a dependency will result in the package being updated.json is generated automatically.Previously, when installing a package, it was necessary to use the -save flag to ensure that the package entry in package was saved.json.

    Uninstall global packages

    If you’ve installed a package globally, you can uninstall it by supplying the -g parameter to the uninstall command when performing the removal.For example, if you have Gatsby CLI installed worldwide and wish to uninstall it, you may do so as follows: npm uninstall -g gatsby is a command-line tool.An very useful command to have on hand is npm prune, which removes any unnecessary packages from your node modules folder.More information will be provided in a subsequent article.

    TL;DR

    • Using npm uninstall, you may automatically delete packages.
    • Manually removing packages should be avoided.
    • Do not verify your node modules in version control
    • instead, use a local copy.
    • Remove any unnecessary node modules with the npm prune command

    How To Reinstall NPM And Node.js On Any System

    • Guy Bar-Gil posted on September 7th, 2020. The Node Package Manager (often abbreviated to npm) and Node.js are two of the most widely used tools among JavaScript programmers. npm is the default package management utility for Node.js, and it is automatically installed on your computer when you download and install the Node.js software. npm is a tool that facilitates in the creation, consumption, management, and sharing of tiny pieces of code. Node.js, on the other hand, provides a server-side environment for developing robust apps. npm, on the other hand, can become corrupted, become incompatible with other applications, or just have performance difficulties from time to time. In such circumstances, reinstalling npm on your machine may be beneficial in order to save yourself the trouble. A similar procedure, reinstalling Node.js, may be beneficial in clearing out any performance issues. Furthermore, because npm is included by default with Node.js, installing Node.js will also result in the installation of npm. In this post, you’ll discover how to reinstall npm and Node.js on three major operating systems: Windows, macOS, and Linux. npm and Node.js are two of the most popular web development tools. The following are the subjects we’ll be discussing: How to determine whether or not a reinstallation was successful
    • How to reinstall npm and Node.js on Windows
    • How to reinstall npm and Node.js on macOS
    • How to reinstall npm and Node.js on Linux
    • Summary

    How to check if reinstallation succeeded

    It’s important to note that, once the reinstallation process is complete, you can verify that it was successful by performing the following instructions on the command line: The system will then report the versions that you have installed if everything went smoothly.Something along the lines of: Because npm is updated more often than Node.js, it is possible that your installation may not include the most recent npm version.As a result, if the npm version you have installed is not the most recent, you may upgrade it by executing the following command: The line above will install the most recent stable version of the npm package manager.On the other hand, if you want to play around with things by utilizing a version that will be released later, you may do so by running the following: For information on how to upgrade Node.js to the most recent version, please see this post.

    How to reinstall npm and Node.js on Windows

    • Npm and Node.js are both capable of being reinstalled and optimized for use in a Windows environment if they are not functioning properly. You can use any of the following strategies to accomplish your goal: Using a Node version manager to reinstall the application
    • Using the Node installer to reinstall Node

    Let’s take them one by one and discuss them.

    a) Reinstalling using a Node version manager

    • Using a Node version manager, you can install multiple versions of Node.js and npm and switch between them without having to restart your computer. nvm-windows is a popular Node version management application that you may use to manage your Node versions. A robust command-line program that allows you to manage numerous Node.js installations in a simple and convenient manner. It is suggested that you delete any existing versions of Node.js and npm from your Windows PC before installing the program. This will avoid any conflicts from occurring during the installation of the program. You may remove them by following the steps outlined below: Uninstall the Node.js software from the Windows Control Panel by selecting it and pressing Uninstall.
    • If there are any Node.js installation folders that are still there, remove them. C:Program Filesmynodejs is an example of a npm install place
    • if any npm install locations are still there, they should be deleted. C:UsersAppDataRoamingnpm is an example of such a path.

    Then, when you’ve cleaned up your system, go to this website and download and execute the most recent nvm-windows installer from there.After it has been installed, you can use the tool to reinstall Node.js and npm by using the Command Prompt or Powershell as an Administrator and running the command.If you wish to reinstall a certain Node.js version, you may do it by using the command line: If you wish to reinstall Node.js version 12.18.0, you may do so by running the following command: If you wish to reinstall the most recent stable Node.js version, you may do so by running the following command: If you wish to see a list of Node.js versions that are currently available for download, you may use the following command: To make advantage of the Node.js version that has been installed in your project, you can switch to it as follows:

    b) Reinstalling using a Node installer

    Using the official Node installer is the quickest and most straightforward method of reinstalling Node.js and npm on your Windows system.To make advantage of this option, you must first visit the Node.js download page and reinstall the most recent Node.js version available.It is advised that you download the version labeled LTS (Long-term Supported) since it has been tested with the NodeJS package manager.It is possible that the version labeled Current, although having the most recent features, will be unstable and unreliable.Following your selection of the version you wish to download and your selection of the Windows Installer option, the installation wizard will magically complete the installation procedure on your behalf.At the end of the process, the installer will automatically overwrite your existing, malfunctioning Node.js version with a newer one.

    How to reinstall npm and Node.js on macOS

    • You’ll need to uninstall any prior versions of Node.js and npm on your macOS system before you can reinstall them. Here are various options for uninstalling them that you may try: This method requires you to manually remove any references to Node and npm from your computer’s OS. Unfortunately, this is a time-consuming operation because there may be several folders containing Node resources. Take, for example, the node executable and node modules folders from /usr/local/lib, delete.npm from the home directory, and many more directories
    • for example,
    • This method includes executing a script to remove Node.js and npm from your macOS system on an automated schedule. Alternatively, you may get a simple script to use here.
    • Using Homebrew—a package management application that allows you to finish the uninstalling procedure quickly and easily—you can get the job done. You may use the following command to get started:
    • Then, once your system has been thoroughly cleaned, you may reinstall Node.js and npm on Mac OS X using any of the following methods: Using the Node installer to reinstall Node
    • Using Homebrew to reinstall the software

    a) Reinstalling using a Node installer

    As previously explained, you may reinstall the tools by using the official Node.js installer. To do so, navigate to the Node.js download page and choose the version you wish to install. Remember to choose the macOS installer option while installing. If you run the installer, it will take care of the rest of the reinstallation procedure for you.

    b) Reinstalling using Homebrew

    In order to reinstall using Homebrew, simply type the following command into the macOS terminal:

    c) Reinstalling using a Node version manager

    You may also use the nvm Node version manager to reinstall the two programs at the same time. nvm can be used on both macOS and Linux systems, so we’ll go over how to utilize it in the next part regardless of which operating system you’re using.

    How to reinstall npm and Node.js on Linux

    To reinstall Node.js and npm on a Linux distribution such as Ubuntu, you’ll need to uninstall any previously installed versions of the frameworks, just like you did in the prior examples. Here are various options for uninstalling them that you may try: You may uninstall Node.js by using the apt package manager, which can be found at: apt-get delete nodejs

    The command above will remove the distro-stable version while retaining the configuration files for future use in the same directory.To remove the package as well as its configuration files, however, you must perform the following steps: Finally, you may uninstall any unwanted packages that were installed automatically with the removed package.These packages include: Using nvm—you can also uninstall Node.js from your system by using the nvm Node version manager.This will be demonstrated in further detail in the following section.

    • Then, once your system has been thoroughly cleaned, you may reinstall Node.js and npm on Linux using any of the options listed below: Using a Node version manager to reinstall the application
    • Using the apt package manager to reinstall the software

    Let’s take them one by one and discuss them.

    a) Reinstalling using a Node version manager

    As previously indicated, you may reinstall Node.js and npm on both macOS and Linux systems by using the nvm Node version manager (nvm).You may use either Wget or cURL to download and install the script-based utility.If you’re using Wget, run the following commands on your terminal: If you’re using cURL, use the following command: The scripts shown above will install the nvm version 0.35.0 on your computer.Remember to always check for the most recent version and to refer to it when running the command you wish to perform.The following commands should be used to determine if it was successfully installed: If everything went according to plan, it would output nvm.nvm is a virtualization tool that you may use to reinstall Node.js on your machine once it has been installed.

    1. Simply run the following command to get started: Run the following command to reinstall a specific Node.js version: For example, the following command will reinstall Node.js version 12.18.0: Once the reinstallation is complete, you can use the following command to make that Node.js version the default system-wide version: Furthermore, by running the following command, you may see a list of Node.js versions that are currently available for download: To uninstall a Node.js version that you’ve installed using the nvm package manager, start by determining if the version is presently active on your system: If it is not currently operating, you can remove it by doing the following steps: The following steps must be taken first if the version targeted for removal is the currently active version: nvm must be deactivated.
    2. Then you may use the uninstall command mentioned above to completely remove it from your system.

    b) Reinstalling using the apt package manager

    Using the apt package manager, you may reinstall Node.js and npm on a Linux distribution such as Ubuntu in a more straightforward manner.You may begin by reloading your local package index, which can be found here: Then, from the repository, reinstall the Node.js version that is considered stable by the distribution: In the vast majority of scenarios, this is all you will need to get started with Node.js.You may also wish to reinstall npm by executing the following command: npm reinstall

    Managing packages — conda 4.12.0.post6+e7012690 documentation

    Note For the commands provided on this page, there are a plethora of alternatives to consider. For further information, check the Command Reference.

    Searching for packages

    For the next instructions, you may either use the terminal or an Anaconda Prompt.To check whether a certain package, such as SciPy, is available for installation, run the following command: For example, to check whether a certain package, such as SciPy, is available for installation from Anaconda.org, run the following command: conda search -override-channels -channel defaults scipy The following command can be used to determine whether a given package, such as iminuit, is present in a specific channel, such as and is accessible for installation: conda search -channeliminuit -override-channels

    Installing packages

    For the next instructions, you may either use the terminal or an Anaconda Prompt.In order to install a specific package, such as SciPy, into an existing environment ″myenv,″ follow the steps below.scipy install -name myenv conda install scipy Without specifying the environment name, which in this case is accomplished by using the -name myenv option, the package is installed into the current environment as follows: Alternatively, you may install a specific version of a package, such as SciPy, by running the command conda install scipy=0.15.0 Installing multiple packages at the same time, such as SciPy and cURL, is accomplished as follows: Note It is preferable to install all of the packages at the same time in order to ensure that all of the dependencies are installed at the same time.Installing numerous packages at the same time while specifying the package’s version is accomplished by using the following command: curl=7.26.0 is installed by conda install scipy=0.15.0.Installing a package for a certain Python version is as follows: conda install scipy=0.15.0 curl=7.26.0 -n py34 env scipy=0.15.0 curl=7.26.0 If you wish to work with a certain Python version, it is ideal to do so in an environment that supports that version of the language.More information may be found at Troubleshooting.

    Installing similar packages

    Installing packages that have similar filenames and fulfill similar functions may result in unexpected effects if they are installed together.The outcome will most likely be determined by the item that was most recently installed, which may be unfavorable.If the names of the two packages change, or if you’re creating variations of packages and need to align other software in the stack, we propose that you use Mutex metapackages to connect them.

    Installing packages from Anaconda.org

    A package management service for both public and private package repositories is provided at annaconda.org, which may be used to retrieve packages that are not yet available through conda install. Anaconda.org is an Anaconda product, in the same way as Anaconda and Miniconda are products of Anaconda. Installing a package from Anaconda.org is as follows:

    1. Navigate to the following address in a browser: Enter the package name bottleneck in the top-left box labeled ″Search Packages″ to locate the package called bottleneck.
    2. Find the package that you’re interested in and click on it to be taken to the detail page for it. The name of the channel is displayed on the detail page of the channel. In this case, the ″pandas″ channel is being discussed.
    3. Now that you have the name of the channel, you may install the package using the conda install command. Run the following commands in a terminal window or an Anaconda Prompt: conda install -c pandas bottleneck It instructs conda to get and install the bottleneck package from the pandas channel on Anaconda.org.
    4. To verify that the package has been installed, execute the following commands in your terminal window or Anaconda Prompt: A list of packages, including bottleneck, displays.

    Note See Managing channels for details on how to install packages from many sources at the same time.

    Installing non-conda packages

    If a package is not accessible from conda or Anaconda.org, you may be able to locate and install the package using conda-forge or another package manager such as pip if the package is not available from conda or Anaconda.org.Pip packages do not contain all of the functionality available in conda packages, thus we recommend that you first try to install any program using conda before using pip.Try searching for and installing the package with the help of conda-forge if the package is not accessible through conda.If you are still unable to install the program, you may try installing it using the pip package manager.While there are some inevitable limitations to the compatibility of pip and conda packages due to the differences between the two packages, conda strives to be as compatible with pip as feasible.Note Both pip and conda are included in Anaconda and Miniconda, so you won’t have to worry about installing them individually.

    1. Virtual environments have been replaced with conda environments, hence there is no longer a requirement to activate a virtualenv before using pip.
    2. It is possible to have pip installed both outside and inside of a conda environment, depending on your preferences.
    3. Installation of pip inside the currently active conda environment and subsequent installation of packages using that instance of pip are required in order to benefit from conda integration.
    4. The command conda list displays packages that have been installed in this manner, with a label indicating that they have been installed via pip.
    5. As explained in Using pip in an environment, you may install pip in the current conda environment by using the command conda install pip in the current conda environment.
    6. Even if there are instances of pip installed both inside and outside of the current conda environment, only the instance of pip installed inside the current conda environment will be utilized unless otherwise specified.

    To install a non-conda package, follow these steps:

    1. Activate the environment in which you wish to run the software by doing the following: Run the command activate myenv in your Anaconda Prompt on Windows.
    2. Run the command conda activate myenv in your terminal window on Mac OS X and Linux.
    1. To use pip to install a software such as See, open a terminal window or an Anaconda Prompt and type the following commands:
    2. Run the following commands in your terminal window or Anaconda Prompt to check that the package was successfully installed: If the package is not shown, install pip as stated in Using pip in an environment and try these commands again.

    Installing commercial packages

    In the same way that you would install any other product, installing a commercial package such as IOPro is no different.Run the following commands in a terminal window or an Anaconda Prompt: conda install -name myenv iopro When you run this command, you will be presented with a free trial version of IOPro, one of Anaconda’s commercial tools that can help you speed up your Python processing.This free trial, with the exception of academic usage, expires after 30 days.

    Viewing a list of installed packages

    For the next instructions, you may either use the terminal or an Anaconda Prompt. To get a complete list of all of the packages currently installed in the active environment, type: To see a complete list of all of the packages in a deactivated environment, type the following into your browser:

    Listing package dependencies

    There isn’t a single conda command that can be used to discover which packages are dependent on a certain package inside your environment. The process consists of the following steps:

    1. List the dependencies that a certain package requires in order to be able to operate: search package name -info with conda
    2. Locate the package cache directory for your installation using the following command: conda info
    3. Identify package dependencies and resolve them. On macOS Catalina, Anaconda/Miniconda defaults to storing packages in the /anaconda/pkgs/ directory (or in the /opt/pkgs/ directory on Windows). Each package contains an index.json file, which contains a list of the packages that it depends on. This file may be found in the directory anaconda/pkgs/package name/info/index.json.
    4. With this information, you may determine which packages are dependent on a certain package. The following command will scan all index.json files in the directory: grep package name /anaconda/pkgs/info/index.json

    Everything that contains the will have its complete package path and version shown as a result of this query.As an illustration, grep numpy /anaconda3/pkgs/*/info/index.json is a command.The following is the output of the previous command: The following information may be found in the index.json file: numpy 1.11.3 py36 0, numpydoc, and numpydoc.json: numpydoc, numpydoc, and numpydoc.json: numpydoc, and numpydoc.json: numpydoc, and numpydoc.json: numpydoc, and numpydoc.json: numpydoc, and numpydoc.Python 3.6.0, version py36 0, located in /Users/testuser/anconda3/pkgs/anconda Information on numpy 1.11.3 py36 0 may be found at -4.3.0-np111py36 0/info/index.json.It is important to note that this also returned ″numpydoc″ since it contains the string ″numpy.″ You can add to your search to get a more targeted set of results.

    Updating packages

    • Use the conda update command to see whether there is a new version of conda available. If conda informs you that an update is available, you will have the option of whether or not to install the update. For the next instructions, you may either use the terminal or an Anaconda Prompt. To make changes to a given package, do the following:
    • To get Python up to date, do the following:
    • To update conda itself, do the following:

    Use the conda update command to see whether there is a new version of the conda distribution.It is up to you whether or not to install an update if conda informs you that one is available.The next steps should be completed via the terminal or an Anaconda Prompt.The following are the instructions for updating a certain package:
    To get Python up to date, perform the following actions:
    Conda itself should be updated as follows:

    Preventing packages from updating (pinning)

    In an environment, pinning a package specification prohibits the updates of any packages specified in the pinned file from taking effect.Add a file entitled pinned to the conda-meta directory of the environment’s conda-meta directory, which contains a list of the packages that you do not want updated.EXAMPLE: If you use the file provided below, NumPy will be forced to stay on the 1.7 series, which is any version that begins with the letter 1.7.This also causes SciPy to remain at the exact same version as before: 0.14.2.Python 1.7.* scipy ==0.14.2 numpy ==0.14.2 In the presence of this pinned file, conda update numpy maintains NumPy at version 1.7.1, whereas conda install scipy=0.15.0 results in an error.The -no-pin flag can be used to overcome the update limitation on a package that has been installed.

    1. Run the following command in the terminal or an Anaconda Prompt: conda update numpy -no-pin Because the pinned specifications are supplied with each conda install, running successive conda update commands without the -no-pin option would restore NumPy back to the 1.7 series of versions.

    Adding default packages to new environments automatically

    To have default packages automatically added to each new environment that you build, follow these steps:

    1. Enter these commands in the Anaconda Prompt or Terminal: conda configuration -add create default packages PACKAGENAME1 PACKAGENAME2
    2. You may now establish new environments, and the default packages will be installed in each of them
    3. you can also delete existing environments.

    You may also add a list of packages to be created by default to the.condarc file, which can be edited. By using -no-default-packages at the command prompt, you may prevent this option from being used by default.

    Removing packages

    • For the next instructions, you may either use the terminal or an Anaconda Prompt. For example, to remove SciPy from an environment such as myenv, run the following command: conda remove -n myenv scipy
    • For example, to uninstall SciPy from the present environment, do the following:
    • To uninstall many packages at the same time, such as SciPy and cURL:
    • To validate that a package has been uninstalled, do the following:

    Uninstall Office from a PC

    The instructions below will walk you through the process of uninstalling Office software from your computer (laptop, desktop, or 2-in-1).See Uninstall Office for Mac if you’re using a Mac.With the Office programs on your computer, uninstalling them will only delete the Office applications from your computer; it will not destroy any of the files, documents, or workbooks that you have generated using the apps.

    Uninstall Office for your installation type

    The procedures required to remove Office are dependent on the type of installation you have on your computer.The most often used installation types are Click-to-Run and Microsoft Windows Installer, which are both described below (MSI).The alternative option is to download and install Office via the Microsoft Store application.Select the Click-to-Run or MSI or Microsoft Store tabs below, and then follow the uninstall instructions for the installation type that you selected in the previous step.Are you unsure of the sort of installation you have?Check your installation type by opening an Office application.

    1. Note: If you are unable to start an application to determine your installation type, first attempt the more common Click-to-Run or MSI uninstall procedures.

    Maintain a record of everything (or it might say Office Account).

        Where does npm install the packages?

        • When installing a package using npm, you have two options: a local install and a global install. A local install is the most common sort of installation.

        By default, when you run a npm install command, such as: BASHnpm install lodash, the command is executed.The package is installed in the current file tree, under the node modules subdirectory of the node modules directory.As a result, the lodash item is added to the dependents property of the package.json file that is now existing in the current folder by npm as well.The following command will do a global installation using the -g flag: BASHnpm install -g lodash is a command line option.When this occurs, npm will not install the package under the local folder, but will instead utilize a global location to store the package.What, precisely, is the location?

        1. Using the npm root -g tool, you can find out exactly where that location is on your computer.
        2. /usr/local/lib/node modules is a possible location on Mac OS X or Linux systems.
        3. On Windows, the path may be C:UsersYOUAppDataRoamingnpmnode modules or something similar.
        4. However, if you are using nvm to handle Node.js versions, the location of the files will change.
        5. For example, if your login is ‘joe’ and you are using nvm, the packages location will be displayed as /Users/joe/.nvm/versions/node/v8.9.0/lib/node modules in the package manager.

        npm Community Forum Archive: npm removes packages on install

        Installation of packageA is performed without storing it to a package. no-save json (–no-save) PackageB should be installed. Both packages have been successfully installed in my node modules directory.

        What Happened Instead

        When packageB is installed, packageA is uninstalled as a result.

        Reproduction Steps

        Gulp -no-save npm install gulp Take note that the term ″gulp″ appears in the node modules directory.gulp-sass may be installed with npm.Take note of the fact that ″gulp″ has been deleted from the node modules directory.Please keep in mind that the packages utilized for reproduction are completely random.Basically, any two packages will operate together as long as packageA is not a dependent of packageB.

        Details

        I understand that this feature may have been planned, but I do not believe it should have been.If someone wants to install a package without saving it to package.json, there are a variety of instances in which they can do so.For example, while using the ″npm link″ command or when installing locally installed packages.If a package has been installed, but it is not included in the package list.When the json and npm install commands are executed, the package will be deleted.

        Platform Info

        This problem may be reproduced using the most recent version of npm (v6.10.3), as well as with prior versions (after v5).This has been verified to work on both Windows 10 and Mac OS X.$ npm -versions npm -versions Test: ‘1.0.0’, npm: ‘6.10.3’, ares: ‘1.15.0’, brotli: ‘1.0.7’, cldr: ‘35.1’, ‘2.8.0’, icu: ‘64.2’, modules: ’64’, napi: ‘4’, ng: ‘1.34.0’, node: ‘10.16.0’, openssl: ‘1.1.1b’, tz process.platform win32 $ node -p process.platform win32 koga73 responded to this question on August 12, 2019.A relevant paragraph was located on: The-no-package-lockargument will prevent npm from writing a package-lock.jsonfile if the option is used.Running npm with the package-locks option turned off prevents it from automatically pruning your node modules throughout the installation process.shadowspawn replied to this post on August 13, 2019.

        1. I understand that this feature may have been planned, but I do not believe it should have been.
        2. I agree that that is exactly as planned.
        3. Though you might alternatively suggest a change in behavior throughideas, or inquire about particular instances throughsupport for methods, thisbugs post will also be read by others.
        4. shadowspawn replied to this post on August 13, 2019.
        5. What is the purpose of this anticipated behavior?
        6. Install commands should not be used to remove packages, especially when the packages being uninstalled are wholly unrelated to the item that is being installed.

        This is a really unexpected behavior, because it makes it virtually hard to create genuinely optional packages in the first place.mykmartin replied to this on August 14, 2019.Once you’ve created a package-lock.json, maintaining it and node modules in sync by default is more helpful than the convenience of storing unsaved changes to node modules, according to what I’ve read.This behavior may be turned off by specifying the command line option —no- package-lock.

        The file package-lock.json is automatically produced for all operations in which npm alters either the node modulestree or the packagjson configuration file.In order for successive installs to build identical trees independent of intermediary dependency changes, it must describe the exact tree that was formed during the first installation process.The package-lock was once adjusted to match the node modules rather than the other way around, however this resulted in even more issues.

        shadowspawn replied to this post on August 14, 2019.As far as I’m aware, npm cannot detect the difference between a package that has been deleted from dependencies in package.json and a package that has been previously installed without saving.That, on the other hand, should only be important when performing a straightforward npm install (i.e.no specific packages requested).

        I’m not sure why npm needs to look at anything else if I’ve specifically requested a single package to be installed; after all, it’s only concerned with ensuring sure that package is appropriately installed.This appears to be especially important when dealing with -no-save installations, because npm isn’t modifying package.json or package-lock.json in that case, and hence shouldn’t be required to sync at all in that case.mykmartin replied to this on August 16, 2019.

        Solving conflicts in package-lock.json

        I wish I didn’t have to spend as much time resolving git conflicts as I do at the moment.It’s time-consuming.It’s prone to making mistakes.It’s just not enjoyable.Solving conflicts in created files, such as package-lock.json, is one task that may be time-consuming and expensive if done incorrectly.It often occurs when two branches add or adjust a dependent on each other.

        1. Package-outcome lock’s changes as a result, and whomever gets their PR merged to main first is the lucky one who avoided those conflicts.
        2. It’s almost as though we’re in a race.
        3. So here you are, updating your PR with the base branch, and git informs you that there are a large number of conflicts in package-lock.json.
        4. What do you do?
        5. It is tempting to simply delete package-lock.json and rerun npm install because the conflicts in package.json are generally easily resolved (if there are any at all).
        6. However, I do not recommend doing so.

        After all, this will result in a whole new package-lock.json file, which you can confidently commit.

        Why you should never delete package-lock.json

        In most cases, when you install a dependent for the first time, it is immediately added to your dependencies or devDependencies with the version prefix, which implies ″compatible with version, according to semver.″ You may see what I’m talking about by clicking here.You may acquire anything from version 4.2.1 to 4.17.20 by entering, for example, lodash as the package and 4.2.1 as the version in your search engine’s search box (the latest version) In this case, the file package-lock.json is used to secure the package.When you first install it, it will ″lock″ you into using the version that you have just installed.As a result, if 4.2.1 is the most recent version available at the time of your installation, this version will be written to package-lock and will be installed on a per-install basis going forward.Even if later versions are released that are technically compatible with it, it is still not recommended.This is significant because it ensures that every developer on the team has the same version of the code on their workstation, and it is also important for continuous integration and delivery (CI/CD).

        1. Even if it’s merely a patch version, I wouldn’t want to release a newer version of the software to production than what we tested with.
        2. As a result, when you erase package-lock.json, all of that consistency is thrown out the door.
        3. You may be certain that any node module on which you rely will be upgraded to the most recent version that it is theoretically compatible with.
        4. This indicates that there will be no big changes, only minor tweaks and repairs.
        5. This, in my opinion, is detrimental for three reasons:
        1. It is predicated on the assumption that everyone rigorously conforms to semantic versioning, which I really doubt is the case. The fact that major version zero is excluded from the requirements of semantic versioning means that there is no method to enforce this. According to the semver specification, major version zero (0.y.z) is intended for starting development. Anything is subject to change at any time. The public API SHOULD NOT be regarded as stable at this time.
