Caroline,
Good idea! There is not a gruntfile.js in my AppDesigner directory, but several of them in subdirectories of the node_module subdirectory, so I copied one of them to my AppDesigner directory and received the message in the screen capture below – are we getting closer? I tried installing that npm module referred to in the message (grunt-contrib-nodeunit) and it did install it somewhere but I get the same error message as below with entering the grunt command.
