How to Uninstall Python
Part of the series, this piece is entitled ″ Published on: Wednesday, July 21st, 2021.The most recent update was made on Wednesday, December 29th, 2021.Bug fixes and security patches are included with every release of the Python programming language.In order to verify that you are not affected by bugs and security issues that have been resolved, it is required to uninstall the previous version.While it is possible to run more than one Python version on the same computer, installing a new version of Python before deleting an older version of Python might cause Python to malfunction on the machine.Fortunately, uninstalling Python before installing the new version resolves the issue, and doing so isn’t too difficult to accomplish.
- Throughout this piece, we’ve laid down how to uninstall Python on every operating system.
How to Uninstall Python From Windows, Mac, And Linux
Python cannot be uninstalled in a typical manner on most operating systems.You will need to follow the uninstallation methods that are unique to the operating system that is currently installed on your computer.Note: You do not need to uninstall Python from your computer if you only wish to remove Python packages from your computer.The pip tool allows you to manage Python packages by adding, removing, and searching for particular ones.When it comes to pip, if you don’t sure where to begin, our comprehensive guide will teach you all you need to know in minutes.
How To Uninstall Python From Windows
Python may be uninstalled quickly and easily in Windows. In three simple steps, you may uninstall any version of Python that is currently installed on your computer.
Step1: Navigate to the Control Panel
To enter the Start menu, hit the Windows key on your keyboard or the Windows button in the bottom-left corner of your screen, whichever is appropriate. Type ″Control Panel″ into the search box and choose and open the Control Panel from the list of possibilities that appears.
Step2: Navigate to the Uninstall Menu
After the Control Panel has been launched, you must select the ″Uninstall an application″ option from the ″Programs″ area on the bottom left of the window that has been shown. A menu containing all of the programs installed on the computer will appear when the machine is turned on.
Step3: Uninstall Python
Scroll through the list of applications until you locate the version(s) of Python that are currently installed on your computer.Select the software you want to uninstall by selecting it with the left-click mouse and then clicking the ″Uninstall″ button.Python will be uninstalled from your computer when the uninstallation procedure has been launched and you have confirmed your decision to delete the program.Python must be removed from the Path variable in order for Python to be totally removed from your computer.
Step4: Remove Python from Path
When the Python uninstaller is executed, it immediately removes Python from the Path variable. Having said that, it is essential to double-check to see whether Python has been deleted from the Path variable. It’s simple and doesn’t take long to complete:
- Press the Windows key and type ″environment variables″ into the search box. To access the settings menu in the Control Panel, click on the Settings button.
- A menu with the title ″System Properties″ will appear. Locate and click on the ″Environment Variables″ button on the toolbar.
- By left-clicking on the ″Path″ variable in the system variables section, you may make it more visible. Then select ″Edit″ from the drop-down menu.
- Selecting the Python bin folder path and tapping the ″Delete″ button on the right side of the menu will remove it from the list of available options.
And with that, you will have completely uninstalled Python from your Windows computer’s hard drive.
How To Uninstall Python From Mac
It is not always a good idea to uninstall Python from a machine running the macOS operating system.This is due to the fact that macOS comes pre-installed with Python, and the operating system relies on Python for many of its internal operations.The Python framework that was pre-installed is located in the /System/Library/Frameworks/Python.framework directory.A number of symlinks may be discovered in the usr/bin/python directory.Removing this version of Python can cause macOS to crash and may even cause the operating system to fail.More information about this may be found at Stack Overflow, a programming-related Q&A site run by Stack Exchange.
- Having said that, if you’ve installed a third-party Python framework on your Mac, you may uninstall it without risk of damaging your computer.
- Here’s how to go about it:
Step1: Remove Python from Applications
Navigate to the Applications folder in the Finder by opening it up.You will discover directories for the Python versions that you have installed in this location.You must dispose of them in the garbage.Keep in mind that if you simply want to delete a certain version of Python from your Mac, you must move the correct Python folder into the Trash.You should input your computer’s password if a dialog box displays requesting you to do so.Once you have entered your password, click ″OK.″ The folders will have been relocated to the Trash folder.
- After that, you must browse to the Trash, select the Python version(s), and right-click to delete them.
- Select the ″Delete Immediately″ option from the drop-down menu that appears.
- Python will not be totally removed from the computer even if the folder is deleted.
- It must be removed from the Library directory, as well as the symbolic links that point to it.
Step2: Remove Python from /Library
Python will need to be removed from the Library directory, and this will be accomplished using the Terminal.To launch Terminal, press Cmd + Space and search for it, after which it will be launched.Remove any third-party frameworks from your directory by typing sudo rm -rf /Library/Frameworks/Python.framework into a Terminal window (or by using the command line).It is possible that you may be prompted to enter your system password.If you are prompted, type it in.For example, if you simply want to delete a certain version of Python from your computer, you may specify that version by altering the command to look like this: sudo rm -rf /Library/Frameworks/Python.framework/Versions/3.8 /Library/Frameworks/Python.framework/Versions/3.8
Step3: Remove Symbolic Links
Python folders and files will have been deleted from your Mac as a result of Steps 1 and 2. However, links to Python folders that have been erased may still exist on your computer if the links point to them. Symbolic links are the names given to these connections (or symlinks). To get rid of these connections from your computer, you can use one of two methods:
1 Manual Deletion
The URLs to the Python folders are located in the /usr/local/bin directory.Due to the fact that the folders that were mentioned in the links no longer exist, the links will no longer function.If you execute the following command in the Terminal, you will get a list of all of your broken symlinks:ls -l./Library/Frameworks/Python.framework’ Please ensure that the path in the above command corresponds to the location you specified in step2 if you have only deleted a certain version of Python.After you have identified all of the broken links, execute the following commands to remove them: To get into the directory, do the following: Remove the broken links by using the following commands: ls -l /usr/local/bin |grep ‘./Library/Frameworks/Python.framework’ |awk ‘Python.framework’ |
- tr -d @ |
- xargs rm * If the path specified in the command above differs from the path specified in step2, the path specified in the command above should be replaced with the path specified in step2.
- Following the execution of these instructions, the Python version that was previously installed on your Mac will be uninstalled.
2 Using Homebrew
Homebrew may also be used to delete the broken symlinks from your computer’s hard drive.If you don’t already have it installed, you may do so by running the following command: /bin/bash -c ″$(curl -fsSL)″ is a shell command.With Homebrew, it is much easy to locate broken hyperlinks.Run the following command to locate them: A list of symlinks that are no longer working will be shown.After that, you may use the following command to get rid of them:
How To Uninstall Python From Linux
Like macOS, Linux has Python pre-installed on the operating system, which is comparable to the way Windows does.Removal of the pre-installed version of the program, on the other hand, causes the operating system to malfunction.When Python is removed from Linux, the Graphical Display Manager is usually unable to function properly.As a result, you can only remove the Python versions that you have explicitly installed on your system.To uninstall the version of Python that you previously installed, use the following command in the Terminal window: sudo apt purge -y python2.x-minimal python2.x-minimal Python 3 may be uninstalled from Linux distributions by using the following command: the command sudo ln -s /usrbin/python3 the command sudo ln -s sudo ln -s To uninstall pip from your machine, run the following command: sudo apt uninstall -y python3-pip the command sudo ln -s../usr/bin/pip3../usr/bin/pip Alternatively, if you discover that the instructions are not functioning, you may need to update your repo list by doing sudo apt get update.And with that, you should be able to remove Python from your computer without any problems.
- You may now install the most recent version of Python on your computer without having to worry about it breaking or having to deal with problems that have already been addressed.
- Make sure to read through our Python installation instructions before proceeding to ensure that you install the new Python version on your machine in a safe manner.

- 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.As you can see in the picture below, Nodemon is listed as a development requirement for the project.I’m going to run npm uninstall –D to get rid of it.
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.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.If you’ve installed a package globally and want to check what you’ve installed, use npm list -g.
You can see that CORS is now labeled as a global package, which is a good thing.I’ll now execute npm uninstall -g cors to remove CORS from the system as a whole.When I run npm list –g, I can see that there is no longer any CORS, which indicates that the command was successful.

How to uninstall Python
Python is removed in a somewhat different way on Windows and Mac computers.
Windows and Mac each have their own method of uninstalling Python.
- Go to the Control Panel and choose it.
- When you click on ″Uninstall a software,″ a list of all the programs that are presently installed will appear.
- To remove a Python version, first choose the Python version that you wish to uninstall, then click the ″Uninstall″ button above the list – this must be done for each Python version that is currently installed on the system.
To get started with Python 3 and above, first complete the following steps:
- Navigate to the Finder and choose Applications from the menu on the left side of the screen.
- Locate the Python folder with the version number of the program you wish to remove, right-click it, and select ″Move to Trash.″
Removing additional files from the Terminal
- Moving the Python program to the trash will not completely remove Python from the system.
- Furthermore, it is possible that a pre-installed Python installation will not display in the Applications directory.
- As a result, we’ll have to manually remove it using the Terminal.
- To begin, open the Activity Monitor and click on the Memory tab to stop any Python-related processes that are running.
The Python Launcher is an example of such a procedure.We’ll be able to travel to the Terminal now.
Open the Terminal and browse to the Library folder in your root directory by typing the following:
- $ is the monetary value of a dollar (base) cd Library is the user name.
- Here, you may use the ls command to see a list of the current folders in your Library.
- Look for a folder with the name Python in it.
- Removing this folder that has super-user access is as follows: rm -rf sudo rm -rf Python Please keep in mind that the procedure cannot be performed without your password.
In addition, three other primary folders must be dealt with in order to completely remove Python.To get back to the root of your computer’s user directory, use the following commands: sudo rm -rf ″/Applications/Python″ sudo rm -rf ″/Library/Frameworks/Python.framework″ sudo rm -rf ″/Library/Frameworks/Python.framework″ rm -rf /usr/local/bin/python /usr/local/bin/python Please keep in mind that this step is not recommended for first-time Mac users.It is possible that the way Python files are distributed in your Library and cache may alter depending on your usage, and that you will need to delete more files that you can look for in the Finder or manually delete in the terminal.
Uninstalling packages and dependencies
Whenever you are no longer need to utilize a package in your code, we recommend that you uninstall it and remove it from the dependencies of your project.
Uninstalling local packages
Removing a local package from your node_modules directory
The uninstall command may be used to remove a package from your node modules directory using the command line interface. If the package has a scope, make sure to include it.
npm uninstall <@scope/package_name>
Removing a local package from the package.json dependencies
The -save switch can be used to remove a package from the dependencies listed in package.json. If the package has a scope, make sure to include it.
npm uninstall -save
npm uninstall -save <@scope/package_name>
Npm uninstall -save lodash npm install -save lodash Note: If you installed a package as a ″devDependency″ (i.e., with -save-dev), you may remove it by using the same -save-dev option: npm uninstall -save-dev package name npm install package name
Confirming local package uninstallation
- Check that the node modules directory no longer contains a directory for the package that was successfully uninstalled to ensure that npm uninstall was a successful operation (s). Unix-based operating system (such as OSX): ls node modules
- Windows systems: dir node modules
- Linux systems: dir node modules
Uninstalling global packages
Uninstall an unscoped global package from the command line by using the -g parameter in conjunction with the uninstall command. If the package has a scope, make sure to include it.
npm uninstall -g
npm uninstall -g <@scope/package_name>
For example, to remove a package named jshint, perform the following command:
Uninstalling local packages
pip uninstall – pip documentation v22.0.4
Unix/macOS pip uninstall may be accomplished using the command python -m pip. python -m pip uninstall-r is the command to use. py -m pip uninstall on the Windows operating system. py -m pip uninstall-r is a Python command.
- Packages can be uninstalled. The pip package manager is capable of uninstalling the vast majority of installed items. The following are examples of known exceptions: The installation of pure distutils packages with python setup.py install, which do not leave any information behind that may be used to detect which files were installed
- Python setup.py develop is responsible for installing script wrappers.
-r, -requirement are both abbreviations for requirements. Remove all of the packages that are specified in the provided requirements file. This option can be used as many times as necessary. -y, -yes, -yeah It is not necessary to obtain confirmation for uninstall removals.
- Uninstalling a package is simple.
- $ python -m pip uninstall simplejson on Unix/macOS Uninstalling simplejson: /home/me/env/lib/python3.9/site-packages/simplejson /home/me/env/lib/python3.9/site-packages/simplejson-2.2.1-py3.9.egg-info /home/me/env/lib/python3.9/site-packages/simplejson-2.2.1-py3.9.egg-info Do you want to proceed (yes/no)?
- simplejson has been successfully removed.
- py -m pip uninstall simplejson in Windows C:> Uninstalling simplejson: /home/me/env/lib/python3.9/site-packages/simplejson /home/me/env/lib/python3.9/site-packages/simplejson-2.2.1-py3.9.egg-info /home/me/env/lib/python3.9/site-packages/simplejson-2.2.1-py3.9.egg-info Do you want to proceed (yes/no)?
simplejson has been successfully removed.
pip freeze Command in Python
- In this post, we will go through the pip freeze command in Python and how it works.
- Consequently, pip freeze is a program that allows you to inspect the modules that have been installed so far with the pip install command.
- Because it shows you the modules you’ve installed using pip install as well as which versions of these modules are now installed on your machine, pip freeze is a highly handy program to have around.
- In Python, there are many things that may be incompatible with one another, such as particular modules being incompatible with one another and so on.
It is possible that you will install the most recent version of Django, but that a prior module that you have installed will no longer be compatible with the newly installed version of Django.As a result, when you run the code, you may get issues.Use of pip freeze to discover what modules and versions of each you have may be quite useful in situations like these, and can even establish whether or not a specific application will function in certain circumstances.Unlike many other commands, pip freeze is a universal command that works on virtually all operating systems, including Windows, Linux, and Mac.
Using the command pip freeze on my Windows PC, for example, I can see what is returned as shown below.This allows you to see all of the modules that I’ve installed on my Windows command prompt using the pip install command, along with their respective versions of those modules.Consequently, you can debug if a specific version of Django, for example, will function with a specific version of a module, and so on and so forth.
As a result, pip freeze is a frequently used command in Python for debugging purposes.Resources that are related
Install, Upgrade, and Downgrade Python 2.7 Packages on Mac and Linux
- Installing a package with pip is as simple as typing pip install.
- Installing the gensim package, for example, may be accomplished using the command ″pip install gensim.″ If you do not have permission to install a package system-wide, you can install the package for yourself by running ″pip install -user gensim.″ Manually installing a package consists of the following steps: (1) get the package; (2) install the package.
- Download the package from PyPi, for example: ″for the gensim package,″ for the gensim package, for example.
- After that, unzip the package and navigate to the location where the package is to be installed using the command ″python setup.py install.″ Installing the package for oneself may be accomplished using the command ″python setup.py install -user.″ To determine the location of the package, run the following command: python -m site.
Ordinarily, the package path on a Mac is ″/Library/Python/2/7/site-packages/″ however this might vary depending on the operating system.When installing Python 2.7 on Linux, the package path is usually something like this: ″/usr/local/lib/python2.7/dist-packages/″ (or ″/usr/lib/python2.7/dist-packages/″).For a local user, the path is ″/home/.local/lib/python2.7/site-packages/″ while for a remote user, the path is ″/home/.local/lib/python2.7/site-packages/″.The following command examines the list of all the packages that have been installed: pip list is an abbreviation for ″pip list.″ Furthermore, the command verifies the version of a specific package: grep |
pip list |grep Both upgrading and downgrading are similar in that they both include two steps: Delete and reinstall the prior package, followed by the current package installation.Pip may be used to update a package: pip install -U.
Manually updating a package consists of the following steps: (1) get the package; (2) install the package.The system will automatically remove the old version of a package when it is updated via pip in some instances.However, in rare circumstances, the system fails to uninstall the previous version, in which case you will need to manually remove the old version from your computer.If you have already updated (upgraded or downgraded) the package, proceed as follows.To find out which version is being used, run ″pip list |grep ″.
It should display the most recent version.However, when you execute a Python program, the system may choose to use an older version; this is likely due to the fact that the system maintains numerous versions and prefers to use the most recent version as the default.The solution is to remove the old version of the file.To be more specific, on a Mac, navigate to the folder ″/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python″ and remove the folder containing the Python package (e.g., gensim).
The system will then utilize the most recent version that has been installed.If the system is unable to locate the package, you will need to re-install the package.If you’re using Linux, navigate to the following folders: ″/home/.local/lib/python2.7/site-packages/″ and ″.local/lib/python2.7/dist-packages/″ (if you’re using Windows, navigate to the following folders: ″/usr/lib/python2.7/site-packages/″).Delete the previous version.

In this article
- The NuGet Package Manager UI in Visual Studio for Windows enables you to quickly install, delete, and update NuGet packages in projects and solutions via a graphical user interface.
- See Including a NuGet package in your project for more information on the Visual Studio for Mac experience.
- Visual Studio Code does not contain the Package Manager UI, which can be found here.
- Note Check Tools > Extensions and Updates and look for the NuGet Package Manager extension if you don’t see it in your Visual Studio 2015.
You may also download the extension from its official website if you are unable to utilize Visual Studio’s extensions installer.When working with any.NET-related workloads in Visual Studio 2017, NuGet and the NuGet Package Manager are now automatically installed.Installing it independently may be accomplished by selecting the Individual components > Code tools > NuGet package management option during the Visual Studio installation process.
Find and install a package
- If you are in Solution Explorer, right-click either References or a project and select Manage NuGet Packages from the context menu.
- The Browse tab displays packages from the currently chosen source based on their popularity (see package sources). You may look for a certain package using the search box located on the upper left side of the page. Click on the name of a package in the list to bring up its details, which also includes an Install button and a version selection drop-down menu.
- Select Install from the drop-down menu after selecting the desired version. Visual Studio adds the package and its dependencies to the project’s source code repository. It is possible that you will be asked to agree to licensing conditions. As soon as the installation is complete, the newly installed packages are displayed on the Installed tab. Also included in the References node of Solution Explorer is a list of packages, indicating that you may refer to them in the project by using statements.
Tip The Include prerelease option should be selected if you want to include prerelease versions in the search and make prerelease versions available in the version drop-down menu.
Uninstall a package
- If you are in Solution Explorer, right-click either References or the relevant project and choose Manage NuGet Packages from the context menu.
- Select the Installed tab from the drop-down menu.
- Select the product to be uninstalled (you may use the search function to narrow down the list if required) and click Uninstall.
- It is important to note that the Include prerelease and Package source controls have no impact when uninstalling packages.
Update a package
- Right-click either References or the relevant project in Solution Explorer and select Manage NuGet Packages from the context menu. (Right-click the Bin folder in web site projects to open it.)
- To see packages that have available updates from the specified package sources, go to the Updates tab and choose them. Include prerelease packages in the update list by selecting Include prerelease packages in the update list.
- Pick the package to be updated, then from the drop-down menu on the right, select the desired version and then click Update.
- When the Update button is disabled for a certain package, a notification displays stating that the package has been ″implicitly referenced by an SDK″ (or ″AutoReferenced″). Because the package is part of a bigger framework or SDK, it should not be updated on its own. (These packages are internally identified by the value True.) If, for example, a package such as Microsoft.NETCore.App is distributed as part of the.NET Core SDK, the package’s version number does not match the version number of the runtime framework used by the application. You must upgrade your.NET Core installation in order to obtain the latest versions of the ASP.NET Core web server and the.NET Core runtime. More information on.NET Core metapackages and versioning may be found in this page. Specifically, this applies to the following frequently used packages: Microsoft.AspNetCore.All
- To update many packages to their most recent versions at the same time, pick them all in the list and then click the Update button above it.
- From the Installed page, you may also update a specific package that has been installed. There is a version selection (subject to the Contain prerelease option) and an Update button in this case, and the package’s details include a description.
Manage packages for the solution
Working with numerous projects at the same time while managing packages for a solution is a simple way to save time.
- Manage NuGet Packages for Solution. from the Tools > NuGet Package Manager menu, or right-click the solution and choose Manage NuGet Packages.:
- You can select the projects that will be affected by the operations when managing packages for the solution through an interface that looks like this:
- The usage of various versions of the same NuGet package across different projects in the same solution is generally considered bad practice by software developers. As soon as you decide to manage packages for a solution, the Package Manager UI gives a Consolidate tab, from which you can quickly identify whether packages with varying version numbers are being utilized by different projects in the solution: For the sake of this demonstration, the ClassLibrary1 project is built using EntityFramework 6.2.0, whereas the ConsoleApp1 project is built using EntityFramework 6.1.0. The following steps should be taken to combine package versions: In the project list, choose the projects that need to be updated
- EntityFramework 6.2.0 is an example of a version that should be used in all of the projects in the Version control system.
- Select the Install button from the toolbar.
In order for the Package Manager to work properly, it must be installed into all specified projects before the package will no longer display on the Consolidate page.
Select one of the following sources from the source selection to modify the source from which Visual Studio acquires packages: To keep track of package sources, do the following:
- Optionally, use the Tools > Options command and scroll down to NuGet Package Manager:
- or choose the Settings icon in the Package Manager UI as shown below.
- Select the Package Sources node from the tree:
- Click on the plus sign (+), modify the name, input the URL or path in the Source control, and then click on Update to finish adding the source. The source is now visible in the drop-down menu of the selection.
- To change the source of a package, select it, make the necessary changes in the Name and Source boxes, and then click Update.
- To turn off a package source, uncheck the box to the left of its name in the list of available sources.
- A package source can be removed by selecting and pressing the X button.
- There is no difference between using the up and down arrow buttons to adjust the priority order of the package sources. Visual Studio does not take into account the sequence in which package sources answer to requests, instead utilizing the package from whatever source responds to requests first. Further information may be found at Package restore.
Tip If a package source returns after being deleted, it is possible that it is listed in a NuGet package at the computer or user level. Config files are files that contain configuration information. See Common NuGet settings for the location of these files, and then delete the source by changing the files manually or using the nuget sources command to remove the source from the package.
Package manager Options control
Following the selection of a package, the Package Manager UI shows a tiny, expandable Options control to the right of the version picker (shown here both collapsed and expanded). It should be noted that for some project kinds, the only available choice is to show a preview window. These alternatives are discussed in further detail in the following sections.
Show preview window
When this option is selected, a modal box appears in which the following dependencies of the selected package are displayed before the package is installed:
Install and Update Options
- The service is not accessible for all project types. It is possible to modify how NuGet determines which versions of dependent packages to install by configuring dependency behavior: Ignore dependencies prevents any dependencies from being installed, which usually results in the package being installed becoming unusable.
- Lowestinstalls the dependency with the lowest version number that satisfies the requirements of the principal package that has been selected
- The Highest Patch option installs the version with the same major and minor version numbers as the current version, but with the highest patch number available. For example, if the version 1.2.2 is supplied, the highest version that begins with the letter 1.2 will be installed
- The Highest Minor option installs the version with the same major version number as the current major version number, but with the highest minor number and patch number. Version 1.2.2 will be installed if it is requested
- otherwise, the highest version that begins with 1 will be installed.
- The highest option installs the most recent version of the software that is currently available.
- When a pa
