I am running a raspberrypi 4B with bookworm (and whichever desktop - X11 or Wayland - that allows it to work with VNC) and writing code in Python. I am trying to read (and maybe eventually write) to other packages using either DBUS or MPRIS(2). I have created a virtual environment ("henry"):-
python -m venv henry
source henry/bin/activate
and then installed pydbus successfully:
pip3 install pydbus
I ran python3, and tried to import pydbus:-
>>> import pydbus
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/hi-pi/Projects/NewElixir/henry/lib/python3.11/site-packages/pydbus/__init__.py", line 1, in <module>

from gi.repository import Gio
ModuleNotFoundError: No module named 'gi'
but I cannot find a way around this.
So I thought I would try to get around this by using MPRIS.
From https://github.com/alexdelorenzo/mpris_server, I followed the instructions, and ran:-
sudo apt install python3-gi
from within the environment, which installed OK, then ran the MPRIS server install:-
pip3 install mpris_server
which gave:-
pip3 install mpris_server
