Exception with python apps

alleyoopster · 11-17-2015, 12:00 AM

I'm running Manjaro and having problems running any python app. When I do it generates at exception as shown in

Code:

Traceback (most recent call last):
  File "/usr/lib/python3.5/site-packages/enum34-1.0.4-py3.5.egg/enum/__init__.py", line 371, in __getattr__
KeyError: '_convert'

During handling of the above exception, another exception occurred:

AttributeError: _convert

I have tried downgrading to 3.3 and 3.4 but then I get errors

Code:

 ImportError: No module named 'gi'

Back to 3.5 and the program fails with the exception.

Any pointers how to fix this please

With some excellent help from The-Compiler on #python at freenode it is now fixed.

Code:

cd /usr/lib/python3.5/site-packages; pacman -Qo * 2>&1 | grep '^error:'

Remove all packages listed from site-packages directory.
