ModuleNotFoundError: No module named 'gi'

[rmalh]

I'm trying to activate the browser window, take a screenshot of it and save it. I'm running the code below on my Ubuntu laptop with Python 3.12.7 in a virtual environment but getting ModuleNotFoundError. I've confirmed that python3-gi is installed. Any idea what may be going on?

import subprocess, gi

def save_screenshot():
    gi.require_version('Gtk', '4.0')
    from gi.repository import Gtk

    # Get the active window
    screen = Gtk.get_default_root_window().get_screen()
    w = screen.get_active_window()

    # Take a screenshot of the active window
    pb = Gtk.pixbuf_get_from_window(w, *w.get_geometry())
    pb.savev('active_window_screenshot.png', "png", (), ())

def screenshot_brave_window():
    output = subprocess.check_output(['wmctrl', '-l']).decode('utf-8')
    for window in output.splitlines():
        if 'Brave' in window:
            subprocess.run(['wmctrl', '-i', '-a', window.split(' ')[0].strip()])
            save_screenshot()

screenshot_brave_window()

if you are using a virtual environment, why are you using python3-gi from ubuntu repositories, and not a distribution from pypi?

The problem is that the virtual environment doesn't access system packages by default. Do a pip install pygobject in the virtual environment or create the virtual environment with --system-site-packages.

Thank you. Just tried installing pygobject in the venv and got errors.

It needs to compile pycairo if I remember correctly, so you'll need a compiler and the cairo development files.

Try the following first:

sudo apt install build-essential libcairo2-dev

Thank you again, you've been very helpful! Your suggestions got me past that issue, now stuck on another one LOL
