pip install mock works but import mock does not - python-2.7

Question

Python 2.7.9 (client requirement), Windows 10
'pip install mock' says it worked
But no mock!
Other modules install and run fine (e.g. coverage) so I'm sure my paths are setup properly
Does mock not install/run on 2.7.9? Having trouble finding requirements for this module.
>pip list
coverage (5.3)
pip (1.5.6)
setuptools (7.0)
UNKNOWN (4.0.2)
>pip install mock
Downloading/unpacking mock
Running setup.py (path:c:\users\user\appdata\local\temp\pip_build_user\mock\setup.py) egg_info for package mock

Running setup.py install for mock
Successfully installed mock
Cleaning up...

>>> import mock
Traceback (most recent call last):

ImportError: No module named mock
Thanks!

Answer 1

you're using a very old version of pip / setuptools which doesn't understand mock's wheels or python_requires or packaging metadata
I'd suggest upgrading pip to at least version 9.0.3 (where python_requires was introduced)
I'd suggest upgrading setuptools to at least version 30.3 (where declarative metadata (setup.cfg) was introduced)
