When I Try To Install 'PyGObject' With pip I Get an Error

Question

When I am trying to install PyGObject I get an error. I am using Python 3.10 and Windows Command Prompt.

C:\windows\system32>pip install PyGObject

  note: This error originates from a subprocess, and is likely not a problem with pip.
  ERROR: Failed building wheel for PyGObject
Failed to build PyGObject
ERROR: Could not build wheels for PyGObject, which is required to install pyproject.toml-based projects

Answer 1

I had the same issue and the problem is that PyGObject needs to be compiled which will be done by default using Microsoft Visual Studio. This seems not to work. I also read somewhere that this won't work. I managed to compile it using the instructions on https://pygobject.readthedocs.io/en/latest/getting_started.html but then got errors importing it into my project ('circular import'). Msys2 relies on python 3.9 by default, while I'm using 3.10. Could be related. Did not have time to look further, yet. So I'm happy for solutions to that :) Maybe will try changing to 3.9. later.
