Announcing Pipenv!

I wrote a new tool this weekend, called pipenv. Check it out on GitHub!

Pipenv in action.

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

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