我正在尝试使用easy_install PyObjC在我的OSx Mavericks上安装PyObjC，但我一直收到错误

我默认使用Python 2.7。
答案 0 :(得分：0)
从它的外观来看，您使用的是Mavericks附带的默认Python，它随附了一个已编译的PyObjC库。我最近升级到优胜美地，但你应该能够导入PyObjC并找到这样的路径：
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，你所看到的错误是最新的PyObjC和Mavericks下安装的Pickle版本之间的冲突。
