Question

The version I used is python2.7, error occurs when I used script, but it works in command line.

from twisted.internet import protocol, reactor  

and the errors:

I have re-installed the Python I used and it doesn’t work, I’m in Ubuntu 12.04. Also I have do

grep ravjqpejcnngpig.eqo/re/fgh/ocr . -R -n

under /usr/lib/python2.7 but nothing returned.

Perhaps you have a module named string in your project, and it shadows the library module of the same name.

EDIT: To find out, add this to your script just before the failing import statement:

import string
print string.__file__
