ModuleNotFoundError: No module named 'gi'

[Lucas-C]

Hi.

I faced this error under Windows, using Cygwin, after installing the package with pip:

$ genxword --help
Traceback (most recent call last):
  File "/usr/bin/genxword", line 7, in <module>
    from genxword.cli import main
  File "/usr/lib/python3.6/site-packages/genxword/cli.py", line 21, in <module>
    from .control import _, Genxword, PY2
  File "/usr/lib/python3.6/site-packages/genxword/control.py", line 24, in <module>
    from .calculate import Crossword, Exportfiles
  File "/usr/lib/python3.6/site-packages/genxword/calculate.py", line 22, in <module>
    from gi.repository import Pango, PangoCairo
ModuleNotFoundError: No module named 'gi'

I should have RTFM, I'm going to try to install the packages mentionned in the README.

I solved the issue by installing the following Cygwin & Python packages (all may not be needed):

$ apt-cyg install gobject-introspection libglib2.0-devel libpango1.0-devel python-cairo-devel python-gi python-gobject-devel
$ pip install PyGObject

That downloaded looots of dependencies though :)

And this time I get another kind of error:

[Lucas-C]

The issue only happened with Python 3, so I switched to Python 2:

$ python2 -c 'import ctypes, sys; ctypes.PyDLL("libpython%d.%d.dll" % sys.version_info[:2])'
$ python3 -c 'import ctypes, sys; ctypes.PyDLL("libpython%d.%d.dll" % sys.version_info[:2])'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python3.6/ctypes/__init__.py", line 348, in __init__
    self._handle = _dlopen(self._name, mode)
OSError: No such file or directory

And it now works !

$ genxword -o "Norwegian Blue" 2000_comwords_ENG.txt n

Well done!

It's good to hear it's still working :)

[Lucas-C]

Yeah, I may not have been very smart to try to install this under Windows. I should have known Cygwin and GTK often don't mix easily :)

By the way I'm writing an article on open source puzzle generators. It will be published in the following weeks on https://linuxfr.org and will mention genxword.

Cool - and thanks for the link.
