Pipenv

Now the official recommendation for managing python dependencies is pipenv

Advantages

  • You no longer need to use pip and virtualenv separately. They work together.
  • Managing a requirements.txt file can be problematic, so Pipenv uses the upcoming Pipfile and Pipfile.lock instead, which is superior for basic use cases.
  • Hashes are used everywhere, always. Security. Automatically expose security vulnerabilities.

Installing

Install on your system:

    pip install pipenv

Install a package

    pipenv install requests
  1. Creates a pipfile
  2. Installs requests
  3. Creates a lockfile

Installing just for development

Use the ---dev parameter

    pipenv install --dev nose2

Then to install with dev packages run:

    pipenv install --dev

Open shell

    pipenv shell

then exit shell instead of deactivate

Use requirements.txt

If you still want to use this relic you can:

    pipenv lock -r

Use with django

To run commands from the environment prefix the command with:

    pipenv run xxx

Eg.

    pipenv run ./manage.py runserver

Personally I don’t like this but perhaps the advantages outway the longer command

Using Pipenv with Visual Studio

Often times we want intellisense from the python virtualenv.

With pipenv and vscode we first need to find where the virtual environment is with:

    pipenv --venv

Then open cmd + shift + p and Select Interpreter and paste the path
