If you are running your application in Visual Studio change the 

import {AppComponent }  from './app.component'

to 

import { AppComponent }  from './app.component.js'

Also change the file extension to .js. and make sure that your file "URL" points to the file.

I encountered the similar problem. After spending about 3 hours, I realized I was running the ng serve command in wrong directory.

Just check your present working directory before starting the angular project.

You should use:

import {bootstrap} from 'angular2/platform/browser'; // <----
import {AppComponent} from './app.component';

bootstrap(AppComponent);

and

import {Component} from 'angular2/core'; // <----

@Component({
  selector: 'hello-world',
  template: '<h1>Hello World From www.angulartypescript.com</h1><h2>Hallo</h2>'
})
export class AppComponent { }

because these modules are explicitly registered by the files you import (https://code.angularjs.org/2.0.0-beta.9/angular2.min.js)
