Python virtualenv12/20/2023 There is no central console (although virtualenvwrapper definitely helps), so tracking and managing multiple virtual environments gets harder the more environments you create.Different versions of Python and different operating systems require different tools to create and work with virtual environments, from pyenv to pywin to virtualenv to venv, and more.You need to have Python 3 (not Python 2, which is officially unsupported by ) already installed before you can create a virtual installation of Python.For example: > pip install pipenv > pipenv install python If you also want to install a version of Python into your virtual environment, you’ll need to use pyenv or pipenv. To deactivate your activated virtual environment, just run the following on the command line: > deactivate You can then pip install Python packages, which will also install the dependencies required for your project into your new virtual_environment. You can up pip to install virtualenv from the Python Package Index (PyPI), and then use it to create and activate a virtual environment by running the following commands from a CMD prompt on a Windows machine: > pip install virtualenv > python3 -m virtualenv C:\Users\project1 > C:\Users\project1\Scripts\activate Virtualenv is a third party package that is popular for creating virtual environments. Today, the best practice is to install Python into a virtual environment to avoid dependency conflicts. If you tried to run more than one project, you could get dependency conflicts if one of your projects requires a different version of a dependency than another project. But this meant that all Python dependencies would be installed centrally in the site-packages directory. ![]() Traditionally, your default Python was installed system-wide (also known as a global install), typically using an installer.
