Cython "ModuleNotFoundError" even though it was just installed via requirements.txt while building docker image

Installing packages when building a docker image via the requirements.txt. In the Dockerfile it reads

COPY requirements.txt /app/requirements.txt
RUN pip3 install -r /app/requirements.txt

In the requirements.txt I put down deploy token for installing a private git repo, such as this example one:

git+https://gitlab+deploy-token-123456:[email protected]/example/lib.git@a1b2c3d4e5f6g7h8j9k1l2m3n4o5p6q7r8s9t

It throws an error, ModuleNotFoundError: No module named 'Cython'.

However, even though I include Cython in the requirements and it gets collected correctly, I get the same error.

Here is the complete message:

I was able to resolve the problem by including

RUN pip3 install Cython

in the Dockerfile, above the requirements installation.
