OSX端口Python库路径？找不到ctypes

我试图使用依赖于ctypes的应用程序，但遇到以下错误：

$ python peach.py -t ~/Desktop/fuzz/wav/template.xml

Traceback (most recent call last):

    import sys, re, types, time, struct, ctypes

    from _ctypes import Union, Structure, Array
ImportError: No module named _ctypes

然后我尝试通过python2.4运行该应用程序，但该应用程序似乎使用了仅在2.5中可用的语法：

$ python2.4 peach.py -t ~/Desktop/fuzz/wav/template.xml 
  File "peach.py", line 498
    finally:
          ^
SyntaxError: invalid syntax

我的python安装也来自OSX端口，我注意到在Peach应用程序中，它将python定义为：

#!/usr/bin/python

如果我的默认python可执行文件指向我的端口安装（我正在运行‘python peach.py’），这会带来什么麻烦吗

这方面有什么办法吗

• python2.5的ctypes
• 是否能够将2.4库添加到2.5路径

ctypes

是自2.5版以来的标准Python库，因此不需要py-ctypes。在我的2.6.5安装中，获取导入错误的行仍然存在

我没有OSX，所以我的问题是：

/opt/local/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5

属于Python 2.5的标准安装，还是可能属于某个框架的坏安装

在运行的python shell中，可以检查

sys.path

的值。可能在标准库之前有一些损坏的库

舍邦行

#/如果usr/bin/python

是像普通程序一样直接调用的可执行脚本的第一行，则操作系统将对其进行解释。在所有其他情况下，这只是一个评论。特别是，如果您在

python myscript.py中调用脚本，或者由其他python代码导入脚本，那么该行将被忽略。
一个简单的解决方案是使用Mac OS附带的本机python构建。这肯定适用于最新版本的MacOSX10.6.4，它包含Python2.6

下面是一个显示正在成功导入“\u ctypes”的示例：

mariah:~ joet3ch$ /usr/bin/python
Python 2.6.1 (r261:67515, Feb 11 2010, 00:51:29) 
[GCC 4.2.1 (Apple Inc. build 5646)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> from _ctypes import Union, Structure, Array
>>>

如果在此之后出现问题，请尝试查看sys.path属性，查看路径中有哪些模块和版本

以下是在新的Mac OS 10.6.4版本上查看sys.path内容的示例：
