What is the best way to install Python packages?
pip is the de facto package manager in the Python world. It can install packages from many sources, but PyPI is the primary package source where it’s used. When installing packages, pip will first resolve the dependencies, check if they are already installed on the system, and, if not, install them.
How to Uninstall Python Packages
Uninstalling packages is a fundamental function provided by all Python package management solutions, including pip, pipenv, and the ActiveState Platform, among others.Package managers, on the other hand, will not deal with transitive dependencies unless they are explicitly declared in a requirements.txt or pipfile.lock file (ie., dependencies of dependencies).Using these widely used tools, we will demonstrate how to remove Python programs in this post.We will also provide an introduction to the ActiveState Platform.In terms of automating the installation and uninstallation of transitive dependencies, the AS Platform is unrivaled.This approach allows you to track conflicts between packages, learn about platform-specific dependencies, and even track system-level requirements such as C and C++ libraries using our dependency management system.
After you have finished reading, you may test drive the ActiveState Platform by registering for a free trial account.To learn how to remove Python packages using the Pip and Pipenv Package Managers, continue reading this tutorial.
Before any packages can be removed, it is important to verify that a Python installation has been set up, which contains the necessary files for removing packages. Requirements for Installation (for Windows).

How to Uninstall Package Dependencies with Pip
The pip command installs a package together with all of the dependencies that the package relies on throughout the installation process. Unfortunately, when you uninstall a package, pip does not uninstall any dependencies that were installed with it. Uninstalling dependencies can be accomplished using a variety of methods, which are detailed below.
If a package has been installed using a pip requirements file (e.g., pip install requirements.txt), all of the packages in requirements.txt can be removed using the following command: pip uninstall requirements.txt
Pip uninstall requirements.txt is a text file that specifies the prerequisites for installing Pip.
For packages that do not include a requirements.txt file, you may use the pip display command to get a list of all the prerequisites for the package in question:
The Pip Show As an illustration, pip demonstrate cryptography The output should be something like this: ‘Requires: six, cffi’ The pip uninstall command may then be used to remove the dependencies that were previously installed. However, before deleting any packages, be sure that they are not dependents on any other already-installed packages on your system.
How to Uninstall Package Dependencies with Pipenv

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:
- As soon as it is invoked, the Python uninstaller removes Python from the Path environment variable. However, it is best to double-check that Python has not been deleted from the Path environment variable (see below). Performing the following task is simple and does not need much time:
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 uninstalled 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.Please let us know if this post was helpful or if you have any suggestions on how we can improve this answer in the comments below.

How to delete an installed module in Python?
- Pip may be used to remove the majority of Python packages that have been installed. For additional information on pip uninstall, please see the following link: For example, if you have the numpy package installed and wish to remove it, you would type the following into the command prompt: Numpy may be uninstalled with pip. There are a few exceptions, however, to this rule. These packages are not readily deleted using the pip package manager: One is pure distutils packages, which are installed using python setup.py install and do not leave any information behind that may be used to discover which files were installed. 2. The script wrappers that were installed by the python setup.py develop script. You will need to manually delete all of the files, as well as undo any other changes that were made during the installation process. To find out what files are included in the installation, you may reinstall the program and look at the list of files that is generated. To create a list of the files that have been installed, use the following command:$ python setup.py install -record files.txt You will now have a list of all of the files in the files.txt file, which you may manually delete from your computer.

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.
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
Development dependencies are packages that are only utilized during the development phase of a project.You must use the -D or -save-dev flags in conjunction with the npm uninstall command in order to remove a development dependency.You must also supply a name for the package you want to remove.To accomplish this, use the npm uninstall -D package-name or npm uninstall -save-dev package-name syntax, which is the most common.Using the command line, go to the directory (folder) where the dependent is located.I’ll be demonstrating how to remove a development dependency using Nodemon.
It allows your NodeJS application to reload automatically whenever a change is detected in a file or folder while in development mode.The Nodemon server is mentioned as a development requirement in the screenshot below.I’ll use npm uninstall –D to get rid of it.nodemon In the package.json file, you’ll notice that Nodemon is no longer there.

Installing, uninstalling, or upgrading Python modules in Linux using Pip
Python modules are packages, or modules, that may be imported into a project and used in that project’s development.Among the numerous packages available are matplotlib, numpy, flask, and many others.You must use Pip to install and uninstall Python packages and modules; PIP is a package manager for Python packages, also known as Python modules.Python modules that are saved on your home computer’s hard drive will only be accessed by you and your computer.Other students, instructors, and staff who require the same packages will be required to perform the following instructions on their own computers in order to participate in shared Python projects.Full-featured RHEL7 Linux systems presently support the Python 2.7, Python 3.4, and Python 3.6 programming languages, which may be launched with the commands ″python″, ″python3.4,″ and ″python3.6,″ respectively.
Determining which version of Pip to use
Determine which version of Python you want to use to install the package. There is a pip management for each version of Python, and you will need to use the pip manager for that version.
|Python Version||Python Command||Pip Command|
The variable ‘$PIP’ should be replaced with the appropriate pip command in each of the following instances. Please keep in mind that the commands python3 and pip3 are presently mapped to the python3.6 and pip3.6 libraries, respectively.
Installing Python packages using Pip
Installing and uninstalling flask will be done as an illustration in this section. Flask is a Python web-development tool that is used for front-end web development.
- Start by opening a terminal window.
- For example, to install a package, run the command ‘$PIP install -user’ where $PIP is the Pip Version command from the preceding table.
- This example will install the flask package.
- ‘pip install -user flask’ is an example of a Python 2.7 command that may be used.
- This would be equivalent to ‘pip3.6 install -user flask’ in Python 3.6.
Using this command will import the flask package, as well as any dependencies that it may have.
Uninstalling/removing Python packages using Pip
- Start by opening a terminal window.
- You can uninstall a package using the command ‘$PIP uninstall’
- however, it is not recommended.
- This example will remove the flask package.
- ‘pip uninstall – flask’ is an example of how to remove flask in Python 2.7.
- This would be equivalent to ‘pip3.6 uninstall -user flask’ in Python 3.6.
Please keep in mind that you will not be able to delete packages that have been installed directly on the system.
Following the listing of the files to be deleted, the program will prompt you for confirmation. Confirm this action by entering the letter ‘y’ followed by the Enter key.
Upgrading a Python package using Pip
If you want to upgrade a Python module, you may use the ‘-upgrade’ flag to do this.
- Start by opening a terminal window.
- In order to upgrade a package, use the command ″$PIP install -upgrade -user″ on your system.
- This example will upgrade the numpy package:
- To demonstrate, we will execute the following command in Python 2.7: pip install -upgrade numpy
- This would be equivalent to ‘pip3.6 install -upgrade -user numpy’ in Python 3.6.
Please keep in mind that you will be unable to update programs that have been installed locally on the system.
Location of installed Python packages through Pip
Pip packages installed with the ‘-user’ flag will be saved in one of the locations listed below in your home directory, depending on the version of Python you are using to install the package: python2.7, python2.6, python2.7, python2.7, python2.7.Please keep in mind that is the location of your home directory, which is also identical to $HOME.~/.local/lib/python2.7/site-packages ~/.local/lib/python3.4/site-packages ~/.local/lib/python3.6/site-packages Python packages installed locally on each system will be saved in one of the following directories by default, depending on the version of python packages you are searching for: By default, Python packages installed locally on each system will be stored in one of the following directories: Python2.7 and Python3.4 and Python3.6 site-packages may be found in the following directories: /usr lib python2.7/site-packages /usr lib python3.6/site-packages
Cleanly managing python modules
When working on a large number of distinct Python projects, it is possible to run into problems due to conflicts between the modules that you have installed.For example, Virtual Environments, which contain everything required to run the program inside of the virtual environment directory, are one method that Python provides for dealing with this problem.Virtual environments are not included by default in Python 2.7; however, there is a module called Virtualenv that may be used to accomplish this.The official Python documentation can be found here, and it demonstrates that Python 3.4 and 3.6 have this capability built-in.The Virtualenv module is also available for Python 3.4 and Python 3.6, as well as for other programming languages.
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:
- The following steps must be followed for Python 3 and higher:
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.
pip freeze Command in Python
$ is the monetary value of a unit of measurement (base) cd Library’s user name is: This is where you may use the ls command to display a list of all of the current folders in your Library.See whether there is a Python folder.It is necessary to delete this folder with super-user permissions: rm -rf – sudo Python Please keep in mind that the procedure will not be performed without your password.
- To completely remove Python, it is necessary to deal with three other primary folders.
- Once you’ve returned to your root user directory, run the following command: Run the following commands to remove Python from your system: sudo rm -rf ″/Applications/Python″ sudo rm -f ″/Library/Frameworks/Python.framework″ rm -rf ″/Library/Frameworks/Python.framework execute rm -rf /usr/local/bin/python sudo rm -rf /etc For beginner Mac users, we do not advocate performing this step.
- Based on your usage, the way Python files are divided in your Library and cache may change.
- As a result, you may need to remove more files, which you can find in the Finder or manually delete in the terminal.
Uninstall Django completely
The problem is with the pip -version or the python -version command.Attempt to resolve the problem using the pip2.7 uninstall Django command.If you are unable to uninstall using the above command, it is likely that your pip2.7 version is not installed, in which case you should follow the procedures listed below: 1)When you run pip2.7, you should see an output similar to this: /usr/local/bin/pip2.7 2) If you do not receive this output, please install pip by running the following commands.
- Get the file pip.py by running sudo python2.7 get-pip.py.
- 3) Now, check your pip version by entering: which pip2.7 is it?
- As a result, you will receive the command /usr/local/bin/pip2.7 as output.
- 4) Use the pip2.7 uninstall Django command to remove Django completely.
- It is possible that the problem is due to the Python version.
- I experienced a similar issue, and here is how I resolved it by uninstalling Django.
- The problem happened as a result of the fact that I had numerous copies of Python installed in my virtual environment.
- $ ls activateactivate this.pyeasy install-3.4pip2.7pythonpython3wheel activate.csheasy installpippip3python2python3.4 activate.fisheasy install-2.7pip2pip3.4python2.7python-config activate.fisheasy install-2.7pip2pip3.4python2.7python-config activate.fisheasy Using the pip uninstall Django command, I discovered that Django was successfully removed from Python 2.7 but not from Python 3.4, therefore I took the following steps to remedy the problem: 1) alias python=/usr/bin/python3 (/usr/bin/python3) 2) Now, using the python -V command, determine your Python version.
- In case you have already changed your Python version, you may simply remove Django by using the pip3 uninstall Django command.
- I hope this has been of assistance.

Uninstalling Anaconda — Anaconda documentation
You may uninstall Anaconda by simply deleting the software from your computer.This will leave a few files behind, which will be OK for the vast majority of people.Take a look at Option A.
- To completely erase all traces of the configuration files and folders from Anaconda and associated applications, you may first download and run the Anaconda-Clean software, after which you can simply remove them.
- Take a look at Option B.
- Option A: To uninstall Anaconda, use the basic remove command as follows: Windows Remove the envs and pkgs folders from the root of your installation by using Windows Explorer before running the uninstall command in the root of your installation.
- Choose Add or Remove Programs or Uninstall a program from the Control Panel, and then pick Python 3.6 (Anaconda) or your preferred Python version
MacOS Start by launching the Terminal.app or iTerm2 terminal program, and then deleting the whole Anaconda directory, which may be named something like /opt/anaconda2/anaconda3/anaconda4. To delete the directory, type rm -rf /anaconda3 on the command line.
Linux Remove your whole Anaconda directory, which may be named anything like anaconda2 or something like anaconda3, by running the command rm-rf /anaconda3 into your terminal window.
- Option B: Complete uninstall using Anaconda-Clean followed by a simple removal. It is important to note that Anaconda-Clean must be done before simple uninstall. Install the Anaconda-Clean package via the Anaconda Prompt (terminal on Linux or macOS) by following the instructions below: conda install the anaconda-clean package
- Run one of the following commands in the same window: All Anaconda-related files and folders should be deleted, with a confirmation prompt appearing before each one is deleted:
- Alternative method of removing all Anaconda-related files and folders without being requested to delete each one:
- Anaconda-Clean produces a backup of all files and directories that may be deleted in a folder named.anaconda backup in your home directory. This backup is stored in the folder named.anaconda backup. Also keep in mind that Anaconda-Clean does not delete any of your data files in the AnacondaProjects directory.
- After running Anaconda-Clean, remove Anaconda by following the steps outlined in Option A above.
Removing Anaconda path from.bash_profile¶
Note that if you are using Linux or Mac OS X, you may also want to look in your home directory for a line such as: export PATH=″/users/jsmith/anaconda3/bin:$PATH″ Note that you should replace the value /Users/jsmith/anaconda3/ with your real path.The path to Anaconda is added to the PATH environment variable by this line.It may refer to either Anaconda or Miniconda, depending on context.
- After uninstalling Anaconda, you may remove this line from the file and store it somewhere.

- Windows PowerShell installation instructions
- and more.
- Alternative installation techniques (which are not encouraged)
- Updating poetry
- Enable tab completion for Bash, Fish, or Zsh
The Poetry package manages dependencies and packages them in a Python-based environment. It enables you to define the libraries on which your project is dependent, and it will take care of the rest (installing and updating them).
Python 2.7 or 3.5 or higher is required for poetry.It is multi-platform, and the objective is to have it operate as well on Windows, Linux, and Mac OS X as it does on other platforms.Remember that Python versions 2.7 and 3.5 will no longer be supported in the next feature release of the software (1.2).
- It is recommended that you consider upgrading your Python version to one that is supported.
Poetry includes a unique installer that will install poetry in a separate location from the rest of your system by vendorizing the dependencies it requires.This is the method that is advised for installing poetry.Note The get-poetry.py script described here will be superseded by the install-poetry.py script in Poetry version 1.2.
- Poetry 1.1.7 and later versions support the usage of this script, which is discussed further below.

- (Invoke-WebRequest -Uri-UseBasicParsing -Uri-UseBasicParsing) Content | python – a programming language Note Poetry is only need to be installed once. It will automatically detect the current Python version and use it to generate virtual environments in accordance with that version. The poetry utility is installed in the Poetry’s bin directory by the installation. On Unix, it may be found at $HOME/.poetry/bin, and on Windows, it can be found at percent USERPROFILE percent.poetry/bin, respectively. By inserting a line to your $HOME/.profile configuration file, this directory will be automatically added to your $PATH environment variable, saving you time and effort (or equivalent files). If you are not comfortable doing so, you may instruct the installation to use the -no-modify-path switch and manually add the Poetry’s bin directory to your path. After that, create a new shell and enter the following commands: It’s time to start using Poetry when you see anything like Poetry 0.12.0 on your screen. Alternatively, if you decide Poetry isn’t for you, you may uninstall it completely from your machine by re-running the installer with the -uninstall option or by setting the POETRY UNINSTALL environment variable before starting the installer. python get-poetry.py -uninstall POETRY UNINSTALL=1 python get-poetry.py -uninstall POETRY UNINSTALL=1 get-poetry.py is a Python script. When Poetry is first installed, it is placed into the user’s platform-specific home directory. If you’d want to modify this, you may set the POETRY HOME environment variable to something like: POETRY HOME=/etc/poetry. get-poetry.py is a Python script. python get-poetry.py -preview POETR
