Hi,
I am rebuilding locally the fenics-dolfinx package in a clean system, and got
the following error
=====================
Configuration error:

============
I noticed that, after installing python3-matplotlib, running a "import gi"
results in a "print(gi.__file__)" printing None.
If I manually install python3-gi as well, then "print(gi.__file__)" will print
the expected path of the system installation of python3-gi.
Is it possible that recent upgrade to matplotlib 3.10 missed a dependency on
python3-gi?
Cheers,
Francesco
