User Testimonials

Jannis Leidel, former pip maintainer—

Pipenv is the porcelain I always wanted built for pip. It fits my brain and mostly replaces virtualenvwrapper and manual pip calls for me. Use it.

Jhon Crypt—

pipenv is the best thing since pip, thank you!

Isaac Sanders—

pipenv is literally the best thing about my day today. Thanks, Kenneth!

☤ Features

• Enables truly deterministic builds, while easily specifying what you want.

• Generates and checks file hashes for locked dependencies (via --hashes).

• Automatically finds your project home, recursively, by looking for a Pipfile.

• Automatically generates a Pipfile, if one doesn’t exist.

• Automatically generates a Pipfile.lock, if one doesn’t exist.

• Automatically creates a virtualenv in a standard location.

• Automatically adds packages to a Pipfile when they are installed.

• Automatically removes packages from a Pipfile when they are un-installed.

• Also automatically updates pip.

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 (to activate a virtualenv, run $ pipenv shell).

eval (env _PIPENV_COMPLETE=source-fish pipenv)
