mkdocs-jupyter plugin installation fails: ERROR: Failed building wheel for pyzmq

[fjp]

Hi, thanks for this github action, it is working great but I have troubles to install a plugin. I am trying to use the mkdocs-jupyter plugin, which depends on pyzmq. I have added a requirements.txt and specified the path the REQUIREMENTS environment variable of this github action. I have also added EXTRA_PACKAGES: build-base. Unfortunately the build fails because of missing headers.

ERROR: Failed building wheel for pyzmq

Any ideas how to fix this issue? I guess I have to install some additional packages?

Thanks and TBH no I don't know why this is the case, maybe @janoszen has an idea?

Running into this as well, might be as simple as adding pip update at the start, see:
