PIP#

Install Packages#

install GIT development code: pip install git+<https_git_clone_link>
install GIT development code from branch: pip install git+<https_git_clone_link>@<branch_name>
install editable local Projects:
- pip install -e .
- also see https://pip.pypa.io/en/stable/reference/pip_install/#editable-installs

List Packages#

list outdated packages: pip list -o
list packages in requirements.txt format: pip list --format freeze

Other Commands#

delete package cache: pip cache purge

Install and update Packages from a File#

For pip you can create so called requirements files. These files just list one package per line. Packages from this file can be installes with pip install -r <requirements.txt> and updatet with pip install -r <requirements.txt> -U. The update only makes sence when you do not specify a version number with the package.

Since pip does not support an “update all” mechanism this is a good way to install and update the needed packages.

To add a package from GIT just add package_name @ git+<https_git_clone_link> instead of the normal package name.
