我默认使用 Python 2.7。

【解决方案1】：

从外观上看，您使用的是 Mavericks 附带的默认 Python，它带有已编译的 PyObjC 库。我最近升级到 Yosemite，但你应该可以导入 PyObjC 并找到如下路径：

Python 2.7.6 (default, Sep  9 2014, 15:04:36) 
[GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.39)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import objc
>>> objc.__path__
['/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC/objc']

我最好的猜测是，您看到的错误是最新的 PyObjC 和安装在 Mavericks 下的 Pickle 版本之间的冲突。
