Python : Pipenv

Qu'est-ce que c'est

Pipenv est une alternative à pip, un peu plus user-friendly et haut niveau. Les modules sont gérées au niveau projet (et non au niveau système !). Il s'installe avec pip et s'utilise comme pip:

<source lang="bash"> [justine@Argonaut ~]$ python3 -m pip install virtualenv --user Requirement already satisfied: virtualenv in ./.local/lib/python3.8/site-packages (20.0.5) Requirement already satisfied: filelock<4,>=3.0.0 in ./.local/lib/python3.8/site-packages (from virtualenv) (3.0.12) Requirement already satisfied: appdirs<2,>=1.4.3 in /usr/lib/python3.8/site-packages (from virtualenv) (1.4.3) Requirement already satisfied: distlib<1,>=0.3.0 in /usr/lib/python3.8/site-packages (from virtualenv) (0.3.0) Requirement already satisfied: six<2,>=1.9.0 in /usr/lib/python3.8/site-packages (from virtualenv) (1.14.0) </Source>

On va créer un dossier pour un projet qui a besoin de divers modules:

To activate this project's virtualenv, run pipenv shell. Alternatively, run a command inside the virtualenv with pipenv run. [justine@Argonaut TestPipEnv]$ ls Pipfile Pipfile.lock </source>
