Here we go again another nightmare

[snippsat]

from urllib.request import urlopen

This only work in Python 3 and you use Python 2.

#Python 3
from urllib.request import urlopen

#Python 2
from urllib2 import urlopen

I can install anything Why? here I try to run a program with 'request in it, this is what i got.

Can not help when we do not know what you do,have you check etree.py.
As sparkz_alot suggests reinstall can be easier,if pip do not work.
