Cannot install Python Package with docker-compose

Question

I am running a Django project with docker. Now I want to install a Python package inside the Docker container and run the following following command:

docker-compose django run pip install django-extra-views

Now when I do docker-compose up , I get an error ImportError: No module named 'extra_views' . docker-compose django run pip freeze doesn't show the above package either.

Am I missing something?

Answer 1

It looks like you ran the pip install in a one-off container. That means your package isn't going to be installed in subsequent containers created with docker-compose up or docker-compose run . You need to install your dependencies in the image , usually by adding the pip install command to your Dockerfile. That way, all containers created from that image will have the dependencies available.
