django-coverage | Yet another django test coverage app | Functional Testing library

I am running a Cookiecutter django project in a docker environment and I would like to add new packages via pip. Specifically I want to add: djangorestframework-jwt

When I do: docker-compose -f local.yml run --rm django pip install it seems like it would be perfectly working because I get: Successfully installed PyJWT-1.7.1 djangorestframework-jwt-1.11.0

Now the problem is that it doesn't install it. It doesn't appear when I run pip freeze, and also not in pip list

Then I tried to put it into my requirements.txt file and run it with: docker-compose -f local.yml run --rm django pip install -r requirements/base.txt

Same result. It says that it is successfully installed but it is not. I thought it might be a problem with my django version and the package, but the same happens when I try to update my pip. It says it updated, but when I run pip install -upgrade pip I get again: You should consider upgrading via the 'pip install --upgrade pip' command.

I'm running out of options.

My requirements:

I am a complete beginner, but I have created a small website using Python / Django with the help of django-cookiecutter, including the deploy to Heroku instructions.

The error message I am receiving is as follows:
