Pipenv is an experimental project that aims to bring the best of all packaging worlds to the Python world. It harnesses Pipfile, pip, and virtualenv into one single toolchain. It features very pretty terminal colors.

It automatically creates and manages a virtualenv for your projects, as well as adds/removes packages from your Pipfile as you install/uninstall packages. The lock command generates a lockfile (Pipfile.lock).

☤ Features

Automatically adds packages to a Pipfile when they are installed.

The main commands are install, uninstall, and lock, which generates a Pipfile.lock. These are intended to replace $ pip install usage, as well as manual virtualenv management.

☤ Basic Concepts

A virtualenv will automatically be created, when one doesn't exist.

When no parameters are passed to install , all packages specified will be installed.

, all packages specified will be installed. When no parameters are passed to uninstall , all packages will be uninstalled.

, all packages will be uninstalled. To initialize a Python 3 virtual environment, run $ pipenv --three first.
