找不到文件<Python.h>

我正在使用Xcode。在这个新的Mac电脑上出现错误'Python.h' file not found.：#include <Python.h>

当我sudo find / -name "Python.h"在命令行中键入命令时，即使在Xcode内部，我也可以看到它存在很多版本。

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk/System/Library/Frameworks/Python.framework/Versions/2.5/include/python2.5/Python.h /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk/System/Library/Frameworks/Python.framework/Versions/2.6/include/python2.6/Python.h /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk/System/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7/Python.h find: /dev/fd/3: Not a directory find: /dev/fd/4: Not a directory /Library/Frameworks/Python.framework/Versions/2.7/include/python2.7/Python.h /System/Library/Frameworks/Python.framework/Versions/2.5/include/python2.5/Python.h /System/Library/Frameworks/Python.framework/Versions/2.6/include/python2.6/Python.h /System/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7/Python.h

任何人都知道发生了什么事吗？是不是我没有正确设置Xcode？
