ImportError: No module named wx, when trying to run app build with py2app

I’m following the instructions starting from “Putting it all together” to create the MacApp.py script and the setup.py script.

http://wiki.wxpython.org/Optimizing%20for%20Mac%20OS%20X

I then run the following command

python setup.py py2app -A

and try to run my application from the terminal

./dist/MacApp.app/Contents/MacOS/MacApp

but I get the following error

Traceback (most recent call last):

File “/Users/me/py2app/dist/MacApp.app/Contents/Resources/boot.py”, line 342, in

_run()

File “/Users/me/py2app/dist/MacApp.app/Contents/Resources/boot.py”, line 335, in _run

exec(compile(source, script, 'exec'), globals(), globals())

import wx

ImportError: No module named wx

2014-01-14 05:46:50.871 MacApp[28921:507] MacApp Error

I am able to run my application from the terminal without issue.

python MacApp.py

Why am I receiving an import error (I also tried included wx in my setup.py file)?
