问题
I've recently started learning GTK+ development and installed some new packages (I don't remember which ones). Now the merge tool meld doesn't work any more:
Cannot import: GTK+
No module named repository
This is caused by line 155 of the meld executable:
from gi.repository import Gtk
Note that I can import gi.repository in Python 3, but it is not so simple to convert meld to Python 3.
How can I fix it?
What I've tried:
sudo apt-get install python-gobject: Was already installed (source)
回答1:
I had the gi package installed:
$ sudo pip uninstall gi
fixed my problem.
回答2:
I just encountered this - but forgot that I was working inside a virtualenv that didn't have this stuff installed. Just needed to run the command from outside the virtualenv.
