Cannot install Python packages due to read-only file system

[yar2001]

Hi, I'm using an add-on that requires the pillow package. However, when I try to install the package, it throws:

ERROR: Could not install packages due to an OSError: [Errno 30] Read-only file system: '/app/blender/4.2/python/lib/python3.11/site-packages/pillow.libs'

Here is the python script I used to install the package:

import pip
pip.main(['install','pillow'])

It seems that the flatpak sandboxed environment is the cause of the problem. Is it possible to solve the problem? Thanks!

Not sure how to install Python package from the python console inside Blender. But I have use something like,

flatpak --command=bash run org.blender.Blender
python3 -mpip install pillow

However, the current build of Blender flatpak does not have pip install. We could do that by changing the manifest from,

"runtime": "org.freedesktop.Platform",
to
"runtime": "org.freedesktop.Sdk",
Other maintainers should let us know what they think about that.
