Python dependency management tool: “Python Development Workflow for Humans.” https://pipenv.pypa.io

Pipenv is a Python tool that aims to bring the best of all packaging / package management worlds (bundler, composer, npm, cargo, yarn, etc.) to the Python world. Windows is a first-class citizen, in our world.

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

The problems that Pipenv seeks to solve are multi-faceted:

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

• Managing a Python requirements.txt file can be problematic, so Pipenv uses the upcoming Pipfile and Pipfile.lock instead, which is superior for basic use cases.

• Python Hashes are used everywhere, always.

• Python Security. Automatically expose security vulnerabilities.

• Give you insight into your Python dependency graph (e.g. $ pipenv graph).

• Streamline Python development workflow by loading .env files.

Usage Examples:

  Create a new project using Python 3.7, specifically:

$ pipenv --python 3.7

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

Install all Python dependencies for a project (including dev):

$ pipenv install --dev

  Create a lockfile containing pre-releases:
  $ pipenv lock --pre

  Show a graph of your installed dependencies:
  $ pipenv graph

  Check your installed dependencies for security vulnerabilities:
  $ pipenv check

  Install a local setup.py into your virtual environment/Pipfile:
  $ pipenv install -e .

  Use a lower-level pip command:
  $ pipenv run pip freeze

pipenv Commands:

• pipenv check - Checks for PyUp Safety security vulnerabilities and against PEP 508 markers provided in Pipfile.

• pipenv clean - Uninstalls all packages not specified in Pipfile.lock.

• pipenv graph - Displays currently-installed Python dependency graph information.

• pipenv install - Installs provided Python packages and adds them to Pipfile, or (if no packages are given), installs all packages from Pipfile.

• pipenv lock - Generates Pipfile.lock.

• pipenv open - View a given Python module in your Python editor.

• pipenv requirements - Generate a requirements.txt from Pipfile.lock.

• pipenv run - Python Spawns a command installed into the virtualenv.

• pipenv scripts - Lists Python scripts in current environment config.

• pipenv shell - Spawns a Python shell within the virtualenv.

• pipenv sync - Installs all Python packages specified in Pipfile.lock.

• pipenv uninstall - Python uinstalls a provided Python package and removes it from Pipfile.

• pipenv update - Runs pipenv lock, then pipenv sync.

• pipenv verify - Verify the hash in Pipfile.lock is up-to-date.
