Jupyter Console 4.1.1

ERROR: Kernel did not respond

Shutting down kernel

After Jupyter Console 4.1.1 it hangs for a while and takes a few minutes before exiting. Any idea what's going wrong? I have brew installed zmq and czmq and tried the wget/mv workarounds listed here to no avail.

this is a result of the zmq module not installing correctly. if that happens, try deleting jupyter-nodejs/node_modules and re-running npm install
