Python configparser error after Yosemite install

Question

I've upgraded to Yosemite and this seems to have broken my python modules.

python --version == Python 2.7.6

Then from the Python shell:

>>> import pyrax
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Python/2.7/site-packages/pyrax/__init__.py", line 38, in <module>
    import six.moves.configparser as ConfigParser
ImportError: No module named configparser

So its complaining about configparser.

pip show configparser
---
Name: configparser
Version: 3.3.0r2
Location: /Library/Python/2.7/site-packages
Requires:

But it is there. After some reading it seems clear that ConfigParser has been renamed to configparser in python version 3. I am however running 2.7.

--- EDIT ----

Some more info:
I'm not using homebrew for Python
I've tried re-installing pyrax

Any ideas ?

I also had broken packages when upgrading from Mountain Lion to Mavericks. If I remember right, I had to reinstall almost all 3rd party packages (mostly via `pip`) to get them to work again. Because of your question, I am now wondering exactly when Apple will get this whole upgrading thing working smoothly. — mach, Oct 21 '14 at 13:18
Running out of options I decided to give this a go: http://stackoverflow.com/questions/2720014/upgrading-all-packages-with-pip . Unfortunately no luck there. — Jason Prawn, Oct 22 '14 at 09:24

Just move the old six out of the way, and reinstall via pip...

mkdir ~/six-old-library/
mkdir ~/six-old-system-library/
sudo mv /Library/Python/2.7/site-packages/six* ~/six-old-library/
sudo mv /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/six* ~/six-old-system-library/
sudo pip install six

I had the same problem and spent a couple of hours investigating it.
I learned that the default python for OS X 10.10 contains an outdated six package.

This is how I fixed it:

Install the python package from homebrew:
```
brew install python
```
Make sure that homebrew python is your default system version. Check brew doctor and your default $PATH:
```
brew doctor
```
Should say "Your system is ready to brew." If it doesn't, you need to fix it first. We need to use homebrew's python, not OS X's python:
```
which python
```
Should output and point to "/usr/local/bin/python"

If it doesn't, check your $PATH - it should output "/usr/local/bin" first, then "/usr/bin". If it doesn't, update it in .bash_profile and/or .zshrc.

Uninstall all your python packages:

pip freeze | grep -v "^-e" | xargs pip uninstall -y

Reinstall all your python packages as needed:
```
pip install -r requirements.txt
```

After all that, it should work.
