Re: Gnumeric and Python (or other scripting languages).

[Frederic Parrenin <parrenin gmail com>]

Hi Jean,

I just decided to give python a try.
I activated the python plugin, opened the python console and entered:

from gi.repository import Gnm

Unfortunately, I got the following error message:

ERROR:root:Could not find any typelib for Gnm
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: cannot import name Gnm

What is going wrong?

Best regards,

Frédéric
