venv

venv

Every python project should have its own virtual environment such that requirements can be managed on a project basis rather than polluting the global pip.

Initialize a virtual environment

python -m venv myvenv

Next, activate it:

source myvenv/bin/activate

Now, one can, e.g., install requirements from a requirements.txt file, which then only will be available within the virtual environment myvenv.

pip install -r requirements.txt

That way, the global pip stays nice and clean.

Finally, deactivate the virtual environment by deactivate to return to the usual shell.
