If you are using rxjs library, then make sure you change the value of
import { Observable } from 'rxjs/Rx';
to
import { Observable } from 'rxjs/observable';
across your workspace
And then make sure you revert/upgrade your typescript to v 2.3.4 and rxjs to 5.6.0. Do a npm clean cache and build again.
This worked for me. It seems there is some problem in compatibility of rxjs library and typescript versions.
Hope this helps.
