pip安装python软件包。这些python包依赖于c库，c库应该由包管理器安装，而不是由pip安装

查看输出时，您缺少几个包的头文件。我能发现这些，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，在软件包管理器中可以看到：

python开发

和

epoll开发

包。但是osx可能有一个简单的方法来实现

---

或者，您可以为您的osx寻找一个预编译包。

看来您已经安装了Xcode 4，它删除了用于构建已安装的Python 2.7的

gcc-4.0

。从回溯中的路径名来看，很可能是从Python.org下载的32位纯Python。对于Xcode 4，您应该尝试安装。然后，您可能需要重新安装已安装的任何软件包，如

Distribute

、

pip

和依赖项。根据Xcode 4的版本，在运行

pip

或

easy\u install

之前，您可能还需要提供以下环境变量设置：

export CC=gcc
