问题
My big problem here is that I'm 1 day into learning MacOSX so the basics need to be explained to me like I'm a 4 yr old.
I'm running OS 10.6, Snow Leopard, which comes with Python 2.6.
The real problem is getting Aptana 2.0 to debug Google App Engine SDK, which I require PIL for image transforming, which requires python 2.5, with the app using the Django-nonrel framework (I realize I didn't make this easy on myself).
I'm already familiar with Python, Google App Engine and Django-nonrel, but getting this setup on a Mac I'm lost.
1) How do I install a 2.5 and not screw up my already install 2.6?
2) How do I change the python path?

回答1:
Easiest way is probably to install Mac Ports: http://www.macports.org/
Then from a terminal window: $ sudo port install python25
Afterwards, you should have python_select available, which you can use to change your symlinks.

10.6 has python2.5 installed, but python2.6 is the default. Use python2.5 manage.py instead of python manage.py.
You can also change default python: defaults write com.apple.versioner.python Version 2.5
Changing the system wide python default may have unintended side affects depending on your setup.
In either situation, you will still want to use easy_install-2.5

I found this stackoverflow answer
Instead of using brew to install into the entire system a really old version of Python; consider using pythonbrew instead. It will isolate the python install - a bit like virtual environment, but for Python itself.
