[Qgis-user] Problem w/ Processing Plugin in Mac

[Michael Treglia]

Hi All,

I have a student trying to work with QGIS on a Mac and is having trouble
starting the Processing Plugin; I'm primarily Windows & Ubuntu user and
thought some Mac users on the list might have some trouble-shooting tips I
can recommend. (It might be something simple - I just haven't encountered
this issue before, and a lot of the options I see on StackExchange are
homebrew focused).

The student is on a fairly recent version of OS 10, and said he installed
QGIS via the downloads (w/ dependencies) available from KyngChaos.

The student first started with 2.12.1-1, and when trying to make sure the
processing plugin was activated/installed, got this error:
Couldn't load plugin 'processing'
ImportError: cannot import name spatialite_utils

I can send the entire traceback if needed, but this is where it seems to
have gotten hung up:

  File "/Users/evan/.qgis2/python/plugins/processing/tools/vector.py",
line 20, in

    from processing.algs.qgis import spatialite_utils

ImportError: cannot import name spatialite_utils

They then tried QGIS 2.8.4-1 (also from KyngChaos), with Processing
throwing the result given at the end of this e-mail. I will be meeting with
the student later today to try a couple of things, but any suggestions of
what might be going on or how to deal with this are welcome. I think for
the 2.8.4, might just need to remove the .qgis folder and start over, but
it would be great to solve the issue in 2.12 also.

Thanks!
Mike
