A Python virtual environment (venv) is an isolated Python installation that allows you to create and manage independent Python environments for different projects. It's essentially a self-contained directory tree that contains a copy of the Python interpreter and various supporting files, enabling you to install packages and manage dependencies without affecting your global Python installation or other projects.
If you hence want to install packages limited to a particular Python project, create a virtual environment for that project. Note that your virtual environments won't have access to globally installed Python packages.
Setup, Activation and Deactivation
To create a virtual environment, you may first have to install the management utility for virtual environments
sudo apt install python3-virtualenv
virtualenv is installed, create up your virtual environment.
venv is the name of your virtual environment in the command below.
Once complete, activate your virtual environment whenever you want to work with it
Note that if you want to leave your virtual environment, you'd have to type
Once a virtual environment is activated (
. venv/bin/activate) packages can be installed via
pip install $PACKAGE_NAME
