Can't import wx(Python) on Mac OS X

问题

It is first time I'm using python on mac. I installed Python 2.7.1 from python.org and then wxPython2.8-osx-unicode-py2.7

(Mac OS X 10.6.6)

I have no idea where they installed to, but anyway, that's what I get:

Python 2.7.1 (r271:86882M, Nov 30 2010, 10:35:34) 
[GCC 4.2.1 (Apple Inc. build 5664)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import wx

回答1:

As FogleBird says, wxPython use 32-bit and Mac Python installer should offer both architectures. So invoking python with 32 bit should allow you to use it with no issue. to invoke Python in 32-bit

$ python2.7-32
Python 2.7.2 (v2.7.2:8527427914a2, Jun 11 2011, 15:22:34) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin

>>> import wx
>>> print wx.version()
2.8.12.1 (mac-unicode)

instead of just $ python

回答2:

You need to use 32-bit Python to use wxPython.

These binaries should work on all versions of OSX from 10.3.9 onwards on either PPC or i386 architectures. Since they use the Carbon API they are limited to running in 32-bit mode.
