App in Angular 2 stuck in Loading
<p>I have been trying to run the app with npm start and to show the Html code I put in the template but doesn't work.
My system setup is the following:</p>

<p><a href="https://i.stack.imgur.com/Z3aXL.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Z3aXL.png" alt="![Project Structure"></a></p>

<p>app.component.ts:</p>

<pre><code>    import {Component} from '@angular/core';

    @Component({
    selector: 'my-app',
    template: '&lt;h1&gt;Display something&lt;/h1&gt;' // &lt;------
    })
    export class AppComponent {}
</code></pre>

<p>app.module.ts</p>

<pre><code>   import { BrowserModule }    from '@angular/platform-browser'
   import { NgModule }         from '@angular/core';
   import { FormsModule }      from '@angular/forms';
   import { HttpModule }       from '@angular/http';

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

@NgModule({
    declarations: [
        AppComponent
    ],
    imports: [
        BrowserModule,
        FormsModule,
        HttpModule
    ],
    providers: [],
    bootstrap: [AppComponent]
})
export class AppModule {}
</code></pre>

<p>main.ts the same as the Angular 2 Quickstart</p>

<pre><code>import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule }              from './app.module';

const platform = platformBrowserDynamic();
platform.bootstrapModule(AppModule);
</code></pre>

<p>index.html extracted from the angular 2 Quickstart</p>

<pre><code>&lt;html&gt;
&lt;head&gt;
    &lt;base href="/   "&gt;
    &lt;title&gt;Proof of Concept v 0.0.2&lt;/title&gt;
    &lt;meta name="viewport" content="width=device-width, initial-scale=1"&gt;

    &lt;!-- 1. Load libraries --&gt;
    &lt;!-- Polyfill(s) for older browsers --&gt;
    &lt;script src="node_modules/core-js/client/shim.min.js"&gt;&lt;/script&gt;
    &lt;script src="node_modules/zone.js/dist/zone.js"&gt;&lt;/script&gt;
    &lt;script src="node_modules/reflect-metadata/Reflect.js"&gt;&lt;/script&gt;
    &lt;script src="node_modules/systemjs/dist/system.src.js"&gt;&lt;/script&gt;
    &lt;!-- 2. Configure SystemJS --&gt;
    &lt;script&gt;
        System.config({
            packages: {
                app: {
                    format: 'register',
                    defaultExtension: 'js'
                }
            }
        });
        System.import('app')
                .then(null, console.error.bind(console));
    &lt;/script&gt;

&lt;/head&gt;

&lt;!-- 3. Display the application --&gt;
&lt;body&gt;
&lt;my-app&gt;Loading...&lt;/my-app&gt;
&lt;/body&gt;

&lt;/html&gt;

<p>Checking the browser console I see the following error:
