Line 30 suggests that pyshark assumes that gevent is installed while line 31 
indicates that gevent is not installed correctly.

So do you have an incomplete install of gevent? Either remove it or replace 
it with a working one, i. e.

import gevent
import gevent._threading

should either both fail or both succeed.
