无法安装任何Python模块，可能是C编译器问题

Question

我在安装/升级python模块时遇到了很多问题。我是新手，所以请记住这一点。现在我尝试安装/卸载Xcode及其命令行工具。我尝试过gcc-osx，但当我必须安装python模块时，似乎什么都不起作用。在

Python有什么问题吗？我也想到了，下载了最新版本。我在macosx小牛，我用过xcode5和xcode4，似乎什么都不管用。问题是error: command 'gcc-4.2' failed with exit status 1？或者这是一种症状？请帮我把头发扯下来试着让这个工作起来。在

编辑：好的，我修正了这个。我不得不完全删除python并重新安装它。现在模块编译！！！在

这里有一个例子：

pip install Cython --upgrade
