Did you install dependencies? Pretty sure describe is a mocha specific function. If you have npm its pretty easy to run an install in console for all the package.json files.

Hope that helps,

yeah ran npm install to grab all of the dependencies. they show in the node_modules driectory

Not sure then, I haven't used Mocha in a little while. This link had some good solutions, I'm not sure which would fix it though


good luck!
