Answer 1

I have spent nearly 1 day to solve this problem. The reason is that there is a mismatch between /usr/lib/python2.7/site-packages/ and /usr/local/lib/python2.7/site-packages/ (for my specific folder tree).

The command to use is as the following:

mv /usr/lib/python2.7/site-packages/* /usr/local/lib/python2.7/site-packages/
rmdir /usr/lib/python2.7/site-packages
ln -s /usr/local/lib/python2.7/site-packages /usr/lib/python2.7/site-packages

I guess you will find 2 /site-packages/ also.

Just for reference for others.
