TypeError: Cannot read property 'apply' of undefined

Sorry I'm probably in over my head here, but:

I am using Pattern Lab Node v1.2.4 on Mac, using the gulp configuration. I just ran sudo npm install, worked fine. (Not sure why i'm forced to do sudo but anytime i run npm install on any project thats the only way to get things installed properly)

When i run gulp patternlab:serve or any other gulp command I get the following:

$ gulp patternlab:serve

Loading engines...
...scanning for engines in the core...
- mustache engine: good to go
...scanning for engines in the edition or test directory...
...done loading engines.

    gulpInst.start.apply(gulpInst, toRun);
