After installing Anaconda, I get constant “KeyError: 'PYTHONPATH'” messages

Question

After installing Anaconda for Python 3.4 on my Mac I get constant messages saying:

Error in sitecustomize; set PYTHONVERBOSE for traceback: 
KeyError: \'PYTHONP         


        

Answer 1

If your PYTHONPATH environment variable is set, unset it. You can check with echo $PYTHONPATH. If it is set it is probably coming from something in ~/.profile or ~/.bash_profile.

The issue is the file /usr/local/lib/python2.7/site-packages/sitecustomize.py. You may want to check what that file is and where it comes from, but removing it should fix the problem.
