An in-depth look at Python’s package management system, pip

April 16, 2015 by Corey Schafer Leave a Comment

In this video, we will take an in-depth look at Python’s package management system, pip. We’ll walk through how to install, uninstall, list, and upgrade packages. We will also dive into how we can output our dependencies and install a list of dependencies.

An in-depth knowledge of pip can be a great addition to your Python tool-belt.

Here is a look at some of the code used in this tutorial:

Install a package

pip install <package_name>

Uninstall a package

pip uninstall <package_name>

Output installed packages to a requirements file.

pip freeze > requirements.txt

Install all packages from a requirements file

pip install -r <name_of_requirements_file>

List installed packages

pip list

List installed packages that need updated

pip list --outdated

Upgrade a package

pip install -U <package_name>

Upgrade all packages (source)

pip freeze --local | grep -v '^\-e' | cut -d = -f 1  | xargs -n1 pip install -U
