pipenv -- менеджер зависимостей PIP и виртуальных окружений Python с множеством других функций.

Возможности:

• Использует Pipfile вместо requirements.txt, что позволяет точно определить версии зависимостей (по хэшу);
• Автоматически устанавливает нужную версию интерпретатора Python, если настроена утилита pyenv;
• Автоматически создает virtualenv в стандартном расположении;
• Автоматически загружает .env-файлы с необходимыми переменными окружения, если он существует;
• Может строить графы зависимостей.

Установка:

pip install pipenv

Использование:

Create a new project using Python 3.6, specifically:

$ pipenv --python 3.6

Install all 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

Locate the project:

$ pipenv --where

/Users/kennethreitz/Library/Mobile Documents/com~apple~CloudDocs/repos/kr/pipenv/test

Locate the virtualenv:

$ pipenv --venv

/Users/kennethreitz/.local/share/virtualenvs/test-Skyy4vre

Locate the Python interpreter:

$ pipenv --py

/Users/kennethreitz/.local/share/virtualenvs/test-Skyy4vre/bin/python

Install packages:

$ pipenv install
