Meteor Angular2 babel - source map generation

Hello,

I'm working on a project using Meteor, Angular2, and babel (among others) using IntelliJ, in windows.  After upgrading our meteor version to 1.3.1, sourcemaps are no longer being generated properly.  I doubt anything in meteor is causing this, only mentioning for context.

I've followed this tutorial: http://blog.jetbrains.com/webstorm/2015/05/ecmascript-6-in-webstorm-transpiling/ and have a File Watcher setup, babel-cli and babel-preset-es2015 installed, and a .babelrc file in the root dir.  When the file watcher runs, I'm getting this error:

SyntaxError: {path omitted}/app.js: Unexpected token (55:0)
 53 | 
 54 | 
> 55 | @Component({
 | ^

My guess is that the babel compiler isn't finding angular2, but I haven't been successful in finding info on how to solve that problem.

Any help would be awesome! (even if it is the end of the day on friday)
