Here is my first simple Hello World
angular 2 app from Angular 2 quick start guide.
import {Component} from \'angular2/core\';
import {bootstrap} fr
adding comment / annotation like shown below solves the problem
//noinspection TypeScriptValidateTypes
bootstrap(AppComponent);
The above answer did not work for me. I was able to fix it by doing what was recommended in the comments above.
bootstrap(<any>AppComponent);
I am using Intellij 14.1.5
For the new angular2 router I had to do ..
bootstrap(AppComponent [
<any>APP_ROUTER_PROVIDERS
]).catch((err:any) => console.error(err));
NOTE any is used on APP_ROUTER_PROVIDERS not AppComponent.
