将Http注入服务时Angular2 [typescript]错误

Question

Sources with problem: https://github.com/clicman/angular2-app/

I`ve tried to inject Http to service and it leads with error:

http:1 Uncaught SyntaxError: Unexpected token <__exec @ system.src.js:1374entry.execute @
 system.src.js:3300linkDynamicModule @ system.src.js:2921link @ system.src.js:2764execute @

    Evaluating http://localhost:3000/angular2/src/http/http
    Error loading http://localhost:3000/scripts/boot.js

Service code:

import {Injectable} from 'angular2/core'
import {Http} from 'angular2/src/http/http';
@Injectable()
export class CommentsService {
  constructor(private _http: Http) { }
  public getComments(): any[] {
    return [];
  }
}

What I do wrong?

您应该将angular2/bundles/http.dev.js到index.html
