Ionic Serve - build dev failed: Cannot read property 'indexOf' of undefined

Wasn't sure where to place this issue - here or in the App Scripts repo. I placed it there - sorry to duplicate

ionic-team/ionic-app-scripts#544

FIXED - I had Firebase as a dependency as well as AngularFire - removing Firebase from package.json fixed the issue.

I don't think this is a long term solution but if you are trying to get 'ionic serve' to work and this is your error you can make a change in a typescript file and save it and then it starts webpack and works. Well works for me and I'm using angularfire2 2.0.0-beta.6 and firebase 3.6.4
