The easiest way to delete a virtual environment in Python is to delete the folder manually. Important: Don’t store your Python scripts and your requirements.txt file inside your Python virtual environment. This is because the $PATH environment variable is modified in the active environment.Īfter activating your Python virtual environment, the bin directory is now at the beginning of the path, meaning that the shell uses your virtual environment’s instance instead of the Python system version. Once you activate your Python virtual environment, you get a different path for the Python executable. If you do not know how to do this, refer to my earlier article on how to create a Python requirements file.īut how does virtualenv work under the hood? You can do so individually or with the help of a requirements.txt file. Now you can install all the packages you need. Like the Mac or Unix environment, it should indicate the mytest directory: Next, you can check that you are in your Python virtual environment with the following command: Now your prompt should be prefixed with the name of your environment in this case, it’s mytest. If you are a Windows user, you can activate virtualenv this way: Next, you can check that you are in a virtual environment with the following command:Īnd that's it! Now you can start installing the required packages for your project. If you are a Mac or Unix user, you can do it as follows: How to Work With and Maintain virtualenv in Pythonīefore installing or using packages in your new Python virtual environment, you need to activate it. You can find more information about virtualenv in the official Python documentation. Seeder FromAppData(download=False, pip=bundle, setuptools=bundle, wheel=bundle, via=copy, app_data_dir=C:\Users\xavie\AppData\Local\pypa\virtualenv) added seed packages: pip=22.0.3, setuptools=60.6.0, wheel=0.37.1 activators BashActivator,BatchActivator,FishActivator,NushellActivator,PowerShellActivator,PythonActivatorĪnd here we go! In the next section, we’ll explore using virtualenv in Python. You will get an output similar to this one:Ĭreated virtual environment CPython3.8.11.final.0-64 in 10455ms creator CPython3Windows(dest=C:\Users\xavie\mytest, clear=False, no_vcs_ignore=False, global=False) Now that virtualenv is installed, let's create a virtual environment in Python called mytest: This is because every Python environment is independent of all the others.Īt their core, virtual environments in Python are just directories containing a few scripts consequently, you can set as many Python virtual environments as you like. With a Python virtual environment for each project, you are free to install different versions of the same Python package for each project. It means that your projects can have their own dependencies – independent of every other project's dependencies. Let’s get started! Install virtualenv in PythonĪ virtual environment in Python allows you to create an isolated environment for your projects. Then we’ll explore how to set up virtual environments in Python and work with repositories. ![]() In this article, we’ll show how to install virtualenv in Python. ![]() It is also an excellent practice to help you write better Python code. This is where setting a virtual environment in Python is very useful. ![]() This becomes a problem because Python cannot differentiate the version number in the site-packages directory. While this does not seem like a big deal at first, things can get difficult if you need different versions of the same library between Project A and Project B. It helps you avoid installing packages globally global installations can result in breaking some system tools or other packages.įor example, let’s say Project A and Project B require the same library. Virtualenv is a tool that allows you to create virtual environments in Python and manage Python packages. Have you tried to install a Python package for a new project, just to see your other projects break because of some compatibility issues? You can avoid this with the help of virtualenv in Python.
