I’m not able to reproduce the problem. Most probably your project is missing a ionic.config.json or it’s not configured properly - create one using the following template. If you’re using TypeScript, you should also add "typescript": true in there.
PS: @jmowright Also I noticed that you’re using pretty old version of Node - I’ll highly recommend you to upgrade Node to the latest LTS or the latest v5-release (however not to Node v6) to avoid compatibility problems with packages that might not support v0.12 anymore.
