I have trouble using pip. For example:
pip install numpy --upgrade
Gives me the following error:
Collecting numpy
Using cached numpy-1.10.2.tar.gz
Exception:

Here are some clues:
(i) I have the same error when I try to run Spyder. It also appears when I try to to install other packages wtih pip, pandas for example.
(ii) I have the feeling, that this is related to the default encoding since sys.getdefaultencoding gives me 'ascii'
Note that it works well if I do it in a virtualenv.
I'm new to ubuntu so I might have done someting wrong.
Setup: python 2.7.6; pip 7.1.2; ubuntu 14.04.03.
Thank you for your help.
I had the same issue. In my case, it comes from a non-standard character in a module description.
I added a
print f.path
in the script
/usr/local/lib/python2.7/dist-packages/pkg_resources/__init__.py
before line 2025, which allowed me to identify the file which was raising an error. It appeared to be the file
/usr/lib/pymodules/python2.7/rpl-1.5.5.egg-info
whose author has a name containing the ö character, which can not be read. I simply replaced the "Göran" with "Goran" in this file and it fixed the problem.
hope this helps.
