[Qgis-user] mac qgis3 binary errors

I think that is the problem.  Towards the bottom of my original email I mentioned that I had only installed python3.6 (from the official source) but not the other options (GUI, command line, pip etc).  I had not realized that any of those were necessary.  I’ll try to reinstall python with pip, then reinstall gdal, and see how that goes….

Interesting.  Now, instead of 4 different error boxes on startup, I just get two:

Couldn't load plugin 'processing' 
ModuleNotFoundError: No module named 'psycopg2' 
and 

Couldn't load plugin 'MetaSearch' due to an error when calling its classFactory() method 
ModuleNotFoundError: No module named 'owslib'

Perhaps there is some other piece missing as well?  Do either of those core plugins require the python UNIX command line, or GUI stuff?  

So, making some progress…

thanks,

--Adam
