I'm trying to workaround conflicting Qt libraries, which are causing Maya to crash. When I run Maya from terminal, I get:

My workaround was to implicitly set up PYTHONPATH environment variable pointing to Qt library:
/Applications/Autodesk/maya2016/Maya.app/Contents/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages
But that's causing other applications using Qt to link to Maya's custom Qt build, producing another conflicts (different builds and Python versions).
I'm guessing that's an OSX-specific question. How to force applications to run their own Qt libraries?
Edit: I removed Qt, PySide and Shiboken packages installed with brew to check if they were picked-up by Maya. With no PYTHONPATH set, PySide is still picked-up from system directories:
import PySide
PySide.__file__
# Result: /usr/local/lib/python2.7/site-packages/PySide/__init__.pyc #
I had the same issue today, and solved it. So this might help.
First check your sys.path from inside maya:
for p in sys.path:
print p
You should now see that it's wrongly listing /usr/local/lib/python2.7/site-packages/
A few reasons:
You are setting the PYTHONPATH in your profile (.bashrc,.profile,.zshrc ...) and running Maya from the command line. In this case you have two options. Either remove the PYTHONPATH from your profile or add an alias that does it for you before running Maya,
Something along those line:
alias maya=export PYTHONPATH="";/App/Maya/macos/maya
You have a .pth file somewhere that link to /usr/local/lib/python2.7/site-packages/. Just check in the list of folders returned by sys.path.
Hope it helps
