Python Install Error: AttributeError: BetterRotatingFileHandler instance has no attribute 'filters'

Question

After trying to install numpy and pandas on my Mac OS 10.6.8 (using python 2.6.1), I ran into a large error that comes up every time I try to install a library (like pandas and numpy). I have not seen it before and I can't google my way out of it.

Here is the error:

Exception:

Any thoughts on what I could do to be able to install libaries (could this be an issue with pip?)

@PadraicCunningham So do you think that its related to some kind of a bug with Python 2.6.1? If so, should I be using a different version of python? — user3736169, Jan 01 '15 at 22:35
To be honest if you are not using 2.6 for some specific reason I would update to the latest which I think is 2.7.9, there have been a lot of improvements and bug fixes since 2.6.1 — Padraic Cunningham, Jan 01 '15 at 22:37
You should definitely be using a different version. If you have to use 2.6, 2.6.9 is the latest. If you don't, consider 2.7.9 or upgrading to 3. — jonrsharpe, Jan 01 '15 at 22:37
@PadraicCunningham, I was told that updating my default python version could mess up some internal mechanisms of my computer, is this totally wrong (just want to double check before upgrading)? — user3736169, Jan 01 '15 at 22:55
There are various approaches, personally I have a /usr/local/bin/python install along with my system python in ubuntu. The real danger would be changing your system default to python3 as it is not backwards compatible.
