Answer 1

您似乎已经安装了 Xcode 4，它删除了用于构建您已安装的 Python 2.7 的 gcc-4.0。从回溯中的路径名来看，很可能是从 python.org 下载的仅 32 位 Python。对于 Xcode 4，您应该尝试安装 latest 64-bit/32-bit OS X installer for Python 2.7 from python.org。然后，您可能需要重新安装已安装的任何软件包，例如 Distribute、pip 和依赖项。根据 Xcode 4 的版本，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。通常这些 python 包依赖于 c 库，这些库应该由你的包管理器安装，而不是由 pip 安装。

查看输出，您缺少几个包的头文件。我可以发现这些可能还有更多..

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

include/python2.7/pyport.h:312

在 ubuntu 上，它是包管理器中的一个简单外观： python-dev 和 epoll-dev 包。但是osx可能有一种简单的方法。

或者你可以为你的 osx 寻找一个预编译的包。
