Error 404 angular2-in-memory-web-api
<p>I would like to use <code>angular2-in-memory-web-api</code> but I get these errors :</p>

<pre><code>GET http://localhost:3000/node_modules/angular2-in-memory-web-api/index.js.map 404 (Not Found)
GET http://localhost:3000/node_modules/angular2-in-memory-web-api/in-memory-backend.service.js.map 404 (Not Found)
GET http://localhost:3000/node_modules/angular2-in-memory-web-api/http-status-codes.js.map 404 (Not Found)
</code></pre>

<p>In the angular2-in-memory-web-api folder I have these files with extension .js and .d.ts but not .js.map</p>

<p>I read this <a href="https://stackoverflow.com/questions/37377529/angular2-tutorial-tour-of-heroes-cannot-find-module-angular2-in-memory-web-a">Angular2 Tutorial (Tour of Heroes): Cannot find module &#39;angular2-in-memory-web-api&#39;</a> and test every solutions but it still doesn't work for me.</p>

<p>Here my code:</p>

<p>boot.ts :</p>

<pre><code>// Imports for loading &amp; configuring the in-memory web api
 import { provide }    from '@angular/core';
 import { XHRBackend } from '@angular/http';
 import 'rxjs/Rx';
 import 'rxjs/add/operator/map';

 import { InMemoryBackendService, SEED_DATA } from '../node_modules/angular2-in-memory-web-api';
 import { FavoriDataBase}               from './favori/favori-database';

 import { bootstrap }      from '@angular/platform-browser-dynamic';
 import { HTTP_PROVIDERS } from '@angular/http';
 import { AppComponent }   from './app.component';

 bootstrap(AppComponent, [
HTTP_PROVIDERS, 
provide(XHRBackend, { useClass: InMemoryBackendService }),
provide(SEED_DATA,  { useClass: FavoriDataBase })]);
</code></pre>

<p>In systemjs.config.js I have this line <code>'angular2-in-memory-web-api': { main: 'index.js', defaultExtension: 'js' }</code>
And in package.json <code>"angular2-in-memory-web-api": "0.0.10"</code>
I also updated <code>angular2-in-memory-web-api</code> in my console.</p>

<p>Everything worked find before I decide to use <code>'angular2-in-memory-web-api'</code>, I was using real http url to catch data and now I need to use "in folder url" to catch data of a created database (initially empty).</p>

<p>My database class:</p>

<pre><code>export class FavoriDataBase {
createDb() {
let database= [];
return {database};
 }
}
</code></pre>

<p>Thanks by advance for any help !</p>
