Python 3: ModuleNotFoundError: No module named 'gi'

[bittner]

According to setup.py this projects runs on both Python 2 and Python 3. However, when I try to install WiX.py from PyPI I do get the following error:

$ pip install WiX.py

I'm running Python 3.6.8 on Ubuntu 18.04.5 LTS. Also, I have both the python-gi and the python3-gi Debian packages installed:

$ dpkg -l | grep -e python-gi -e python3-gi
ii  python-gi           3.26.1-2ubuntu1     amd64      Python 2.x bindings for gobject-introspection libraries
ii  python3-gi          3.26.1-2ubuntu1     amd64      Python 3 bindings for gobject-introspection libraries
ii  python3-gi-cairo    3.26.1-2ubuntu1     amd64      Python 3 Cairo bindings for the GObject library

I can import the gi module in my Python 2.7, though, so it's likely that installing with Python 2 will succeed:

$ python
Python 2.7.17 (default, Jul 20 2020, 15:37:01)
[GCC 7.5.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import gi
>>>

The project doesn't seem to have a test suite and pipeline to test against supported Python versions. Is there any documentation saying which requirements must be satisfied for Python 3 installations?

I see that there are 2 PRs open, #15 and #17. Can they be merged?

Installing with the changes from #17 worked for me:

$ pip install git+https://github.com/shimondoodkin/wixpy@patch-1#egg=Wix.py

$ wix.py
