Pipenv Quick Start

pipenv, authored by the creator of requests, wraps virtualenv, pip, and Pipfile management into a single tool for project-specific environments.

Install

pip install pipenv

Create an environment

Run inside your project directory:

pipenv --two

Use --two for Python 2 or --three for Python 3. On Windows you may need to point at the interpreter explicitly:

pipenv --python "C:\Python27\python.exe"

Install dependencies

pipenv install

This reads Pipfile / Pipfile.lock. If neither exists, pipenv converts requirements.txt automatically. Install a package explicitly:

pipenv install six

After adding packages, refresh the lockfile:

pipenv lock

Activate the env

pipenv shell

Notes

• You can still run pip inside the environment, but it will not update Pipfile.
• Pipenv cannot magically fix packages that fail to install under virtualenv.
• Pipenv stores environments in a central directory. When you run pipenv shell it looks for a matching folder based on the current path; if none exists it assumes the project has no environment.
