Pipenv

  • PipEnv is an upgrade over pip. It doesn't come with Python by default, so you'll need to install it first.
  • Two major benfits over pip are:
    • Dependencies are installed in a virtualenv, so you don't have to worry about installing them in the system path.
    • It automatically captures installed dependencies in files to generate an exact replica of the environment packages.
      • I'd then check the dependeinces file into my code repository and is always available for me to use and share.
      • Unlike in pip where you specifically need to freeze a snapshot of the entire virtual env with all of its dependencies.
      • It generates 2 files: Pipfile and Pipfile.lock
