Docker build different in Github Actions - docker

Question

When I build my docker file locally and push my application runs correctly. However when I Build through github actions I get an error that 'flask' is not installed.
It seems that the pip install step does nothing in Github actions - it just shows:
Step 8/13 : RUN pip install --trusted-host pypi.python.org -r /app/requirements.txt
---> Running in 6b0816c1bdc8
Removing intermediate container 6b0816c1bdc8
However on my local i get the full pip install output..
Is there something I am missing with Github Actions?
