virtualenv

Instead of the built-in venv module, virtual environments can also be managed with the PyPI package virtualenv. It offers some additional features and is for instance used by pipenv and poetry.

Usage

The syntax to manage virtual environments is similar to venv.

$ virtualenv .venv           # create new virtual environment .venv
$ source .venv/bin/activate  # activate the virtual environment .venv
$ deactivate                 # deactivate the current virtual environment

When juggling multiple Python versions, you can specify the python executable for the virtual environment.

$ virtualenv -p python3.11 .venv    # create .venv for the given python interpreter
