问题
Meld used to work on my machine (openSuse Linux 13.1, Python 2.7.6) but after having trouble with Spyder (like it refusing to actually run any scripts), I uninstalled a large number of things, then slowly brought them back again.
Since then, meld does not work anymore. I keep getting this error message
> meld
Cannot import: GTK+
No module named gi
I was able to solve that by installing gi:
> pip install gi
Now the error is replaced by:
> meld
Cannot import: GTK+
No module named repository
... and here is a similar question where uninstalling gi apparently helped? I'm confused. I did try uninstalling it again but that just brought me back to the previous error (duh!).
Any ideas?
回答1:
OK, that was not obvious:
gi.repository is not part of gi but its own thing. That's why gi should not be installed (thank you Moose).
This article then pointed me to a possible source, python-gobject. However, I already had that installed. So I installed other things that looked similar, and the python-gobject-cairo package ( Python 2.7, openSuse 13.1) did the trick. Seems like someone overlooked a dependency for Meld...

I unlinked the file that was showing in Expected in:
Expected in: /Applications/Meld.app/Contents/Frameworks/libz.1.dylib
unlink /Applications/Meld.app/Contents/Frameworks/libz.1.dylib

After changing python3 from version 3.7 to 3.6 error disappeared.
I have done that by:
sudo apt-get install python3.6
sudo rm /usr/bin/python3
sudo ln -s /usr/bin/python3.6 /usr/bin/python3
