The default JSHint output is somewhat wasteful, and very bland, making it hard for a human to parse. The following does IMO a better job and colours the output for you. This requires the `colors` package, available via npm. If you don't want the dependency, just remove the color commands from strings. MIT licence.

* jshint someFile.js --config /path/to/config.cfg --reporter /path/to/jshintReporter.js | |

Trying this out and I got the same error as @akvadrako above, except without any errors.
Double-checked the path the to the file and made sure it's accessible.
