cb is not a function

[dgrim1214]

Despite following the installation instructions for hubot and hubot-ector, I have been unable to make it work. Upon launching hubot, I receive these two errors:

Error while loading cn.json
Error: ENOENT: no such file or directory, open 'cn.json'

Then, during operation of the bot, any string not caught by other hubot scripts will return

ERROR TypeError: cb is not a function

Oh, yes. This is due to bug in node-ector's dependencies. See parmentf/node-ector#4
When I'll have the energy, I'll fix the dependency.
In the interval, you can always modify the package.json of the node-ector node_module, by removing the ^ character on the concept-network line...
Then go to the directory of node-ector, and run npm install.

Sorry for the inconvenience.
