Installing Dependencies

Intro​

For dependency management we simply use pip from within the docker container.

There is a requirements/ directory that contains dependency lists for dev, test, staging, prod as well as a base dependency list that is included by all the environments.

Adding a Dependency​

To add a new dependency to the project, first install it with pip.

pip install some_new_dependency

And then to get the version that you need to put in the requirements files, run:

pip freeze | grep some_new_dependency

# should output something like this:
# some_new_dependency==1.2.3

Then simply place that line into the relevent requirements file.

  • requirements/base.txt for dependencies that installed in all environments.
  • requirements/dev.txt for development only dependencies.
  • requirements/{staging,prod}.txt for staging/prod only dependencies.
  • requirements/test.txt for testing only dependencies.
