npm install inside cordova-js is needed to resolve a local grunt issue

Could you elaborate this quirk please @brodybits? Could not reproduce.

If I do not do npm install inside cordova-js before running createmobilespec.js then it fails with an error message that it could not find a local grunt. This is what I remember, at least.

Ok, I did not encounter this. We will have to reproduce this again and see if it was a one-off problem for you or is an actual problem.

I just tried removing generated node_modules from my cordova-js project and encountered this issue again on my mac. I hope I get a chance to try it on Windows someday.
