Pipenv: Python Development 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. Windows is a first--class citizen, in our world.
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.
精华版
pipenv = pip + virtualenv + Pipfile&Pipfile.lock
