NAME
pipenv - Python package manager based on virtual env and Pipfiles
SYNOPSIS
NOTE:
This guide is written for Python 3.7+
MAKE SURE YOU HAVE PYTHON AND PIP
Before you go any further, make sure you have Python and that it’s available from your command line. You
can check this by simply running
$ python --version
You should get some output like 3.10.8. If you do not have Python, please install the latest 3.x version
from python.org
Additionally, make sure you have pip available. Check this by running
$ pip --version
pip 22.3.1
If you installed Python from source, with an installer from python.org or via Homebrew, you likely
already have pip. If you’re on Linux and installed using your OS package manager, you may have to
install pip manually.
INSTALLING PIPENV
Preferred Installation of Pipenv
It is recommended that users on most platforms install pipenv from pypi.org using
$ pip install pipenv --user
NOTE:
pip user installations allow for installation into your home directory to prevent breaking any
system-wide packages. Due to interaction between dependencies, you should limit tools installed in
this way to basic building blocks for a Python workflow such as virtualenv, pipenv, tox, and similar
software.
If pipenv isn’t available in your shell after installation, you’ll need to add the user site-packages
binary directory to your PATH.
On Linux and macOS you can find the user base binary directory by running python -m site --user-base and
appending bin to the end. For example, this will typically print ~/.local (with ~ expanded to the
absolute path to your home directory), so you’ll need to add ~/.local/bin to your PATH. You can set your
PATH permanently by modifying ~/.profile.
On Windows you can find the user base binary directory by running python -m site --user-site and
replacing site-packages with Scripts. For example, this could return
C:\Users\Username\AppData\Roaming\Python37\site-packages, so you would need to set your PATH to include
C:\Users\Username\AppData\Roaming\Python37\Scripts. You can set your user PATH permanently in the Control
Panel.
You may need to log out for the PATH changes to take effect.
To upgrade pipenv at any time:
$ pip install --user --upgrade pipenv
Homebrew Installation of Pipenv
• Homebrew is a popular open-source package management system for macOS (or Linux).
Once you have installed Homebrew simply run
$ brew install pipenv
To upgrade pipenv at any time:
$ brew upgrade pipenv
NOTE:
Homebrew installation is discouraged because it works better to install pipenv using pip on macOS.
INSTALLING PACKAGES FOR YOUR PROJECT
Pipenv manages dependencies on a per-project basis. To install a package, change into your project’s
directory (or just an empty directory for this tutorial) and run
$ cd myproject
$ pipenv install <package>
NOTE:
Pipenv is designed to be used by non-privileged OS users. It is not meant to install or handle
packages for the whole OS. Running Pipenv as root or with sudo (or Admin on Windows) is highly
discouraged and might lead to unintend breakage of your OS.
Pipenv will install the package and create a Pipfile for you in your project’s directory. The Pipfile is
used to track which dependencies your project needs in case you need to re-install them, such as when you
share your project with others.
For example when installing the requests library, you should get output similar to this:
$ pipenv install requests

To activate this project's virtualenv, run pipenv shell.
Alternatively, run a command inside the virtualenv with pipenv run.
USING INSTALLED PACKAGES
Now that requests is installed you can create a simple main.py file to use it:
import requests
response = requests.get('https://httpbin.org/ip')
print('Your IP is {0}'.format(response.json()['origin']))
Then you can run this script using pipenv run
$ pipenv run python main.py
You should get output similar to this:
Your IP is 8.8.8.8
Using $ pipenv run ensures that your installed packages are available to your script by activating the
virtualenv. It is also possible to spawn a new shell that ensures all commands have access to your
installed packages with $ pipenv shell.
VIRTUALENV MAPPING CAVEAT
• Pipenv automatically maps projects to their specific virtualenvs.
• By default, the virtualenv is stored globally with the name of the project’s root directory plus the
hash of the full path to the project’s root (e.g., my_project-a3de50).
• Should you change your project’s path, you break such a default mapping and pipenv will no longer be
able to find and to use the project’s virtualenv.
• If you must move or rename a directory managed by pipenv, run ‘pipenv --rm’ before renaming or moving
your project directory. Then, after renaming or moving the directory run ‘pipenv install’ to recreate
the virtualenv.
• Customize this behavior with PIPENV_CUSTOM_VENV_NAME environment variable.
• You might also prefer to set PIPENV_VENV_IN_PROJECT=1 in your .env or .bashrc/.zshrc (or other shell
configuration file) for creating the virtualenv inside your project’s directory.
