尝试启动iPython / jupyter笔记本崩溃，发出以下错误：

ImportError: dlopen(/Library/Python/2.7/site-packages/zmq/backend/cython/constants.so, 2): Library not loaded: /opt/local/lib/libzmq.3.dylib 
Referenced from: /Library/Python/2.7/site-packages/zmq/backend/cython/constants.so

在此处追踪解决方案：

安装pyzmq出了问题但是通过macports或pip卸载然后重新安装没有摆脱问题文件。

从/Library/Python/2.7/site-packages/删除zmq目录，然后使用pip重新安装修复此问题。
