Pycharm "Note that you cannot install any Python packages into Docker-based project interpreters."

in the docs it sayes "Note that you cannot install any Python packages into Docker-based project interpreters." so what is the alternative for that?

The + button to add packages it dimped and I can't click it to add packages, despite it work very well when I use vertualenv instead of docker compose, or docker.
