尝试运行gevent socketio示例（Django）

Question

我遇到了以下错误：

(virtenv3)iMac:codysoyland-django-socketio-example-d35672f admin$ python run_example.py 
Traceback (most recent call last):

这个错误是什么意思呢？我在安装这个示例所需的所有依赖时没有遇到任何问题。

greenlet、cython、libevent、gevent、gevent-socketio、gevent-websocket这些都安装得很顺利。

你是用llvm编译libevent的吗？我记得在homebrew的配方里（在它切换到libevent2之前）有个指令是“不要用llvm编译”，因为出现了这个错误。
