did u tried python3-gi? – Suavity

There are MANY (as in thousands!) questions about ModuleNotFoundError already. Could you please try to make this question unique and clear? You wrote that you already tried a virtual environment. That's good. Could you edit your question and describe the exact commands you used to create and activate that environment, the exact command you used to run the Python script, and the exact output of that command? With that information, it will be pretty simple for others to reproduce the issue and answer the question. – Durazzo

Note that this answer already provides some explanation and solutions for installing and using Python packages in WIndows. This solution might apply to your question as well, but maybe not. It's hard to tell without more information. NB: Please also add which module you are trying to use (link to pypi?) – Durazzo

I think this seems to fully answer the question: Python cannot install PyGObject If so, this question should be closed as duplicate. – Durazzo

NB: official installation instructions for PyGObject are here – Durazzo

Answer 1

Try this:

sudo apt install libcairo2-dev libxt-dev libgirepository1.0-dev

pip install pycairo PyGObject

can it work on windows ? – Vasya

This error comes up in the last stage: ModuleNotFoundError: No module named 'cairo._cairo' – Jeb

I also needed sudo apt install libpython3.10-dev (replace 3.10 with the version of python you are using). – Calais

Answer 2

In an Arch based distro, this worked for me. You can use another AUR helper such as Pamac or Yay instead of Paru.

paru -S gobject-introspection 
pip install pygobject

On some Arch setups with externally managed Python environments, installing the pacman package python-gobject instead of running that pip commands is necessitated. – Sabadilla

Answer 3

On a RHEL8 variant (Rocky Linux 8) the resolution was to use /usr/bin/python3.6m instead of regular python3.6 (or any of the other Python variants I had installed which did not end with an 'm').

More info on 'm' variants can be found here: What's the difference between python3.<x> and python3.<x>m

Answer 4

I got my python setup properly trashed on Ubuntu 20.04. I was trying to use apt-add-repository and got "ModuleNotFoundError: No module named 'gi'". I had already installed software-properties-common and python3-gi using apt. For me the answer was

sudo apt-get --reinstall install python3-gi

Answer 5

Bit late on the answer but I am having the same problem in 2023. I have the same problem with a python installation as user in /usr/local/bin instead of /usr/bin. Hope this helps someone
