首先，我尝试临时将 /Library/Python/2.6/site-packages/pyobjc_core-2.2-py2.6-macosx-10.6-universal.egg/ 移动到其他地方并尝试 import 语句再次。这将使操作系统能够默认导入操作系统附带的 objc 版本（位于 /System/Library 中）。通过使用 /System/Library 中的版本，它对我有用：

>>> import objc
>>> print objc.__file__ 
/System/Library/Frameworks/Python.framework/Versions/2.6/Extras/lib/python/PyObjC/objc/__init__.pyc

您也可以考虑将 /opt/local/lib/libiconv.2.dylib 移动到其他地方。它看起来已经过时了，OS X Snow Leopard 在 /usr/lib IIRC 中有自己的 libiconv.2.dylib 副本。

First I'd try to temporary move /Library/Python/2.6/site-packages/pyobjc_core-2.2-py2.6-macosx-10.6-universal.egg/ to somewhere else and try the import statement again. This will enable the OS to import the version of objc that came with the OS by default (this is in /System/Library). By using the version in /System/Library, it works for me:

>>> import objc
>>> print objc.__file__ 
/System/Library/Frameworks/Python.framework/Versions/2.6/Extras/lib/python/PyObjC/objc/__init__.pyc

You might also consider moving /opt/local/lib/libiconv.2.dylib to somewhere else. It looks outdated and OS X Snow Leopard has its own copy of libiconv.2.dylib in /usr/lib IIRC.
