上一篇讲到，我需要安装PonyDebugger，而安装PonyDebugger需要安装pybonjour，然而，安装pybonjour时，又遇到了错误，错误信息如下， Traceback (most recent call last): File “setup.py”, line 32, in import pybonjour File “/Users/huangshaojun/Downloads/Eichhoernchen-pybonjour-c63b48c/pybonjour.py”, line 109, in _libdnssd = ctypes.cdll.LoadLibrary(_libdnssd) File “/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/ctypes/__init__.py”, line 443, in LoadLibrary return self._dlltype(name) File “/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/ctypes/__init__.py”, line 365, in __init__ self._handle = _dlopen(self._name, mode) OSError: dlopen(libSystem.B.dylib, 6): image not found

我到github上也找到了对应的Issue 192 https://github.com/square/PonyDebugger/issues/192 Issue提到的解决方法是

well, okay i had to do a brew install python

即，不要用OSX内置的python，而用brew新安装一个python。

我并不想再新安装一个新的python，我还是希望用OSX内置的python，为此，我根据 http://stackoverflow.com/questions/32905322/oserror-dlopenlibsystem-dylib-6-image-not-found 的提示，修改了pybonjour.py

将

if sys.platform == 'darwin':
        _libdnssd = 'libSystem.B.dylib'
    else:

改为

if sys.platform == 'darwin':
        _libdnssd = '/usr/lib/libSystem.B.dylib'
    else:

这样用OSX内置的python就可以正确安装pybonjour了。
