Hi there,
This seems to be related to this topic, but with Pillow instead of numpy.
Alpine has a system package called py3-pillow. So configuration should look like this:
system_packages:
- py3-pillow
- ffmpeg
python_packages: []
init_commands: []
As you can see Pillow should not be included as a python package, but as a system package now.
Regards,
Xavi M.
