I undid this. I removed all those exports from my ".bash_profile". Now I get a 
different warning and error:


$ python3 img-clear-metadata.py 

** (process:1495): WARNING **: 13:11:20.340: Failed to load shared library

Using Python and GExiv2

[sirgazil]

Hi,

I used to use a python script to clear image metadata in Debian:


import gi
gi.require_version("GExiv2", "0.10")
from gi.repository import GExiv2


metadata = GExiv2.Metadata("/tmp/something.png")
metadata.clear()


I'm trying to make this work in the GNU system I installed with Guix, but I 
haven't been able to. So far, I have installed the following packages with guix:

gobject-introspection 1.56.1
python 3.70
python-pygobject 3.28.3
gexiv2 0.10.10

I've also added the output of "guix package --search-paths" to my 
".bash_profile".

However, when I run the script above, I get the following error:


$ python3 img-clear-metadata.py 
Traceback (most recent call last):
  File "img-clear-metadata.py", line 2, in 
gi.require_version("GExiv2", "0.10")
  File 
"/home/sirgazil/.guix-profile/lib/python3.7/site-packages/gi/__init__.py", line 
130, in require_version
raise ValueError('Namespace %s not available' % namespace)
ValueError: Namespace GExiv2 not available


I don't know what I'm missing...


I'm using this guix:

$ LANG=C guix describe
Generation 3Jun 15 2019 09:49:31(current)
  guix ddd401d
repository URL: https://git.savannah.gnu.org/git/guix.git
branch: master
commit: ddd401d28fb09f1f8ce96f2fc24226887a812412
