After updating ionic and attempting to serve I received a failure as shown below. I have since attempted to revert the update, but the problem persists:

Relevant code (from the first error listed):

```
import * as Rx from "../../../../node_modules/@reactivex/rxjs/src/Rx";
...
Rx.Observable
    .create(observer => {
        facebookConnectPlugin.login(["public_profile", "user_birthday"],
            data => {
                observer.onNext(data);
                observer.onComplete(data);
            },
            observer.onError
        )
    })

```

And the line it is complaining about from Rx:  
`import Observable from './Observable';`

Both should be valid typescript. It appears webpack or the typescript loader is having a fit.  
Is there any clear solution to this failure?

I fixed the problem by manually including secondary dependencies and fixing the npm reference path. I’m not sure why it wasn’t working, but it is resolved now.
