PIP How-To

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_file.txt> and updatet with pip install -r <requirements_file.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.

Install GIT development code

pip install git+<https_git_clone_link>
 
# for branch_name:
pip install git+<https_git_clone_link>@<branch_name>

To put it into a requirements file just add this: git+<https_git_clone_link> instead of the normal package name.

FAQ

Wo speichert pip die Pakete unter Linux?

Die Pakete werden unter ~/.local/lib/<python_version>/site-packages/ gespeichert. Dieses gilt natürlich nur wenn pip ohne Environment-Manager wie zum Beispiel conda genutzt wird.
