title: Angular2 Cannot find module 'angular2/core' but application works
body: <p>Given I have app written in Angular2 with <code>app.component.ts</code> and some imports in it:</p>
  
  
  
  <pre><code>import {Component} from 'angular2/core';
  
  import {FiltersService} from "./services/filters-service";
  import {SearchPipe} from "./pipes/header-pipe";
  import {PaginationPipe} from "./pipes/pagination-pipe";
  
  
  import {Header} from "./components/header/header.component";
  import {Pagination} from "./components/pagination/pagination.component";
  import {ConfigService} from "./services/config-service";
  import {ResourceService} from "./services/resource-service";
  import {HttpService} from "./services/http-service";
  
  import 'rxjs/add/operator/map';
  import {GlobalSearch} from "./components/global-search/global-search.component";
  import {GlobalSearchPipe} from "./pipes/global-search-pipe";
  import {CsvExport} from "./components/dropdown/csv-export.component";
  import {HTTP_PROVIDERS} from "angular2/http";
  </code></pre>
  
  <p>When I start app by <code>npm start</code>, the app is starting and works properly, but in the console I am getting:</p>
  
  <pre><code>app/app.component.ts(1,25): error TS2307: Cannot find module 'angular2/core'.
  app/app.component.ts(18,30): error TS2307: Cannot find module 'angular2/http'.
  </code></pre>
