Cannot import in python2.7

[Alessandro Tanasi]

I am totally unable to use this library in python 2.7.
With the latest ubuntu package i am unable to:

>>> from gi.repository import GExiv2

I got a:

ImportError: cannot import name GExiv2

# python2.7
Python 2.7.4 (default, Sep 26 2013, 03:20:56)
[GCC 4.7.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from gi.repository import GExiv2
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named gi.repository

The import works well with python3.

# python3
Python 3.3.1 (default, Sep 25 2013, 19:30:50)
[GCC 4.7.3] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from gi.repository import GExiv2
>>>

But if i try to locate:

$ locate GExiv2.py
/usr/lib/python2.7/dist-packages/gi/overrides/GExiv2.py
/usr/lib/python3/dist-packages/gi/overrides/GExiv2.py

# dpkg -l| grep exiv

This was reported by Alessandro upstream at http://redmine.yorba.org/issues/7582

Robert Park replied to your problem, Alessandro, suggesting you try installing python.gi. Hve you tried that?

[Alessandro Tanasi (jekil)]

Yes, it solved. Why this is not a package requirement?

[Jim Nelson (yorba-jim)]

Because gexiv2 is not a Python library, it's designed for many languages to use.

Perhaps the Python bindings should be packaged separately with the appropriate dependencies in place, but I'm not sure of that. For example, gexiv2 also ships with Vala bindings, but it doesn't (nor should it) require Vala to be installed.

[Robert Bruce Park (robru)]

Yeah, it's a bit tricky. Technically in order to use everything installed by gexiv2, we'd need to depend on both python-gi and python3-gi. But then that would require *everybody* to have *both* python2 and python3. Well, not everybody has python3, and hopefully soon there will start to be people who don't have python2! I guess those things could be added as Recommends: but they should not be hard deps.
