Pipenv-Python Dev Workflow for Humans

Pipenv is a tool that aims to bring the best of all packaging worlds (bundler, composer, npm, cargo, yarn, etc.) to the Python world.

You no longer need to use pip and virtualenv separately. They work together.

It automatically creates and manages a virtualenv for your projects, as well as adds/removes packages from your Pipfile as you install/uninstall packages. It also generates the ever-important Pipfile.lock, which is used to produce deterministic builds.

Install Pipenv

brew install pipenv

Getting Started

• Install/uninstall dependencies and virtualenv

pipenv install/uninstall
pipenv shell

• shell will spawn a shell with the virtualenv activated.
• run will run a given command from the virtualenv, with any arguments forwarded (e.g. $ pipenv run python).
• check asserts that PEP 508 requirements are being met by the current environment.
• graph will print a pretty graph of all your installed dependencies.

Usage Examples

Create a new project using Python 3.7, specifically:
pipenv --python 3.7

Remove project virtualenv (inferred from current directory):
pipenv --rm

Locate the project:
pipenv --where
