Pipenv: Python Dev 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.
Pipenv is primarily meant to provide users and developers of applications with an easy method to setup a working environment. For the distinction between libraries and applications and the usage of
Pipfile to define dependencies, see ☤ Pipfile vs setup.py.
The problems that Pipenv seeks to solve are multi-faceted:
You no longer need to use
virtualenvseparately. They work together.
requirements.txtfile can be problematic, so Pipenv uses
Pipfile.lockto separate abstract dependency declarations from the last tested combination.
Hashes are used everywhere, always. Security. Automatically expose security vulnerabilities.
Strongly encourage the use of the latest versions of dependencies to minimize security risks arising from outdated components.
Give you insight into your dependency graph (e.g.
$ pipenv graph).
Streamline development workflow by loading
You can quickly play with Pipenv right in your browser:
Install Pipenv Today!¶
If you already have Python and pip, you can easily install Pipenv into your home directory:
$ pip install --user pipenv
Or, if you’re using Fedora 28:
$ sudo dnf install pipenv
It’s possible to install Pipenv with Homebrew on MacOS, or with Linuxbrew on Linux systems. However, this is now discouraged, because updates to the brewed Python distribution will break Pipenv, and perhaps all virtual environments managed by it. You’ll then need to re-install Pipenv at least. If you want to give it a try despite this warning, use:
$ brew install pipenv
More detailed installation instructions can be found in the ☤ Installing Pipenv chapter.

- David Gang—
This package manager is really awesome. For the first time I know exactly what my dependencies are which I installed and what the transitive dependencies are. Combined with the fact that installs are deterministic, makes this package manager first class, like cargo.
- Justin Myles Holmes—
Pipenv is finally an abstraction meant to engage the mind instead of merely the filesystem.
☤ Pipenv Features¶
Enables truly deterministic builds, while easily specifying only what you want.
Generates and checks file hashes for locked dependencies.
Automatically install required Pythons, if
Automatically finds your project home, recursively, by looking for a
Automatically generates a
Pipfile, if one doesn’t exist.
Automatically creates a virtualenv in a standard location.
Automatically adds/removes packages to a
Pipfilewhen they are installed or uninstalled.
.envfiles, if they exist.
The main commands are
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).
A virtualenv will automatically be created, when one doesn’t exist.
When no parameters are passed to
install, all packages
[packages]specified will be installed.
To initialize a Python 3 virtual environment, run
$ pipenv --three.
Otherwise, whatever virtualenv defaults to will be the default.
graphwill show you a dependency graph of your installed dependencies.
shellwill spawn a shell with the virtualenv activated. This shell can be deactivated by using
runwill run a given command from the virtualenv, with any arguments forwarded (e.g.
$ pipenv run pythonor
$ pipenv run pip freeze).
checkchecks for security vulnerabilities and asserts that PEP 508 requirements are being met by the current environment.
