Assumpte: [DNG] tryng to install virt-manager on Devuan 4 : ModuleNotFoundError: No module named 'gi'
Hello to everyone.

I've installed virt-manager on Devuan 4 installed on my ARM
chromebook,because it is very comfortable to use it to virtualize the
various guests. Unfortunately,when I run virt-manager I get this error :


root@devuan:~# virt-manager
Traceback (most recent call last):
File "/usr/bin/virt-manager", line 6, in <module>
from virtManager import virtmanager
File "/usr/share/virt-manager/virtManager/virtmanager.py", line 15, in
<module>
import gi
ModuleNotFoundError: No module named 'gi'


Google a little bit I found this post :


https://askubuntu.com/questions/80448/what-would-cause-the-gi-module-to-be-missing-from-python


where there are 3 solutions to fix the problem,that I tried,but none of
them worked.


1.

The simple way:

sudo apt install python3-gi -----> python3-gi is already the newest
version (3.38.0-2).

2.

The vext <https://stackoverflow.com/a/43808204/5209935> way, for
virtualenv users:

   pip install vext : ERROR: Exception:

The pure Python developer way:

Install a bunch of developer stuff:

sudo apt install pkg-config libcairo2-dev gcc python3-dev
libgirepository1.0-dev

Install the python package:

   pip install PyGObject : root@devuan:~# pip install PyGObject
   ERROR: Exception:

       raise CalledProcessError(retcode, process.args,

What else can I try ?
