Answer 1

您似乎已经安装了Xcode 4，它删除了用于构建已安装的Python 2.7的gcc-4.0 。 从traceback中的路径名，很可能是从python.org下载的32位Python。 使用Xcode 4，您应该尝试从python.org安装最新的用于Python 2.7的64位/ 32位OS X安装程序 。 然后，您可能需要重新安装已安装的任何软件包，例如Distribute ， pip和dependencies。 根据哪个版本的Xcode 4，您可能还需要在运行pip或easy_install之前提供以下环境变量设置：

export CC=gcc

Answer 2

pip安装python包。 Ofthen那些python包依赖于c libaries，它们应该由你的包管理器安装，而不是由pip安装。

查看输出中缺少的几个包头文件。 我可以发现这些可能会有更多......

conftest.c:1:23: error: sys/epoll.h: No such file or directory

include/python2.7/pyport.h:312

在ubuntu上，它是包管理器中的简单外观： python-dev和epoll-dev包。 但是osx可能有一个简单的方法。

或者，您可以为您的osx寻找预编译的包。
