If reinstall setuptools:

sudo pip install setuptools -I
OR
wget https://bootstrap.pypa.io/ez_setup.py -O - | sudo python 

[ref](https://bitbucket.org/pypa/setuptools)

and build pip from source via

sudo python setup.py install

File "setup.py", line 6, in <module>
    from setuptools import setup, find_packages
  File "/usr/local/lib/python2.7/dist-packages/setuptools/__init__.py", line 11, in <module>
    from setuptools.extern.six.moves import filterfalse, map
  File "/usr/local/lib/python2.7/dist-packages/setuptools/extern/__init__.py", line 1, in <module>
    from pkg_resources.extern import VendorImporter
ImportError: No module named extern

@StevenLOL I would try running

$ pip uninstall setuptools
$ pip uninstall distribute

Do this a couple of times, in order to try to remove all traces of these projects.

Then you can reinstall, e.g with

$ wget https://bootstrap.pypa.io/get_pip.py -O - | sudo python 

OR

After you could try reinstalling the system copy of setuptools, e.g

$ sudo apt-get install --reinstall python-setuptools

wow, thanks @Ivoz

This seems fixed the problem

apt-get install --reinstall python-setuptools
