We are using pip-tools for better dependency management.
All commands are supposed to be executed from your virtual environment!
To install the dependencies into your virtual environment, use the command pip-sync.
This will install/upgrade/uninstall everything necessary to match the requirements.txt contents. This way we can ensure all virtual environments perfectly reflect the requirements.txt file.
The generated requirements files will include "transitive dependencies" (dependencies of our dependencies) and show for each dependency metadata of the "why" it was installed as comments.
If you wish to get a clearer picture of the dependency tree, you can use the command pipedtree
To add a development or production dependency, use respectively the dev-requirements.in and requirements.in files. Always make sure to pin the version of the dependency.
For this dependency to be added to the dev-requirements.txt and requirements.txt files, we use pip-compile:
pip-compile requirements.in # Prod dependencies
pip-compile dev-requirements.in # Dev dependencies
