angular - rc1 路由器 "No provider for Router"

这是@Shuhei 帮助我解决 config.js 问题后出现的错误的跟进帖子 angular 2 rc router angular2-polyfills.js:349 Error

这是我的 app.component.ts

import { Component,provide }       from '@angular/core';
import { RouteConfig, ROUTER_DIRECTIVES,Router } from '@angular/router-deprecated';

import { HeroShellComponent } from '../apps/hero/hero-shell.component';
import {HomeComponent} from '../home/home.component';

import {Login} from '../login/auth.component';
import {Authentication} from '../login/auth.service';
import {isLoggedin}  from '../login/auth.isLoggedin';

@Component({
  selector: 'my-app', 
  templateUrl: 'app/appshell/app.component.html',
  styleUrls: ['app/appshell/app.component.css'],
  directives: [ROUTER_DIRECTIVES],
})

@RouteConfig([
    {
        path: '/app/apps/hero/...',
        name: 'Hero Sample',
        component: HeroShellComponent,
    },
    { path: '/app/apps/testapp1', name: 'Testapp1', component: HomeComponent },
    { path: '/', redirectTo: ['Login'] },
    { path: '/home', name: 'Home', component: HomeComponent },
    { path: '/login', name: 'Login', component: Login, useAsDefault: true },   
])
export class AppComponent {

  title = 'Apps';

  constructor(public _auth: Authentication, 
              public router: Router
              ) {}  

  onLogout() {

    this._auth.logout();
    this.router.navigate(['/Login']);
  }

}

所有其他组件都像上面这样通过构造函数注入(inject)路由器。 当然提供了路由器。

path: '/app/apps/hero/...'

用于子路由器重定向。

我得到的错误是

browser_adapter.ts:78 EXCEPTION: Error: 
Uncaught (in promise): EXCEPTION: Error in :0:0 
ORIGINAL EXCEPTION: No provider for Router!. 

ORIGINAL STACKTRACE: Error: DI Exception 
at NoProviderError.BaseException [as constructor] (npmcdn.com/@angular/core@2.0.0-rc.1/src/facade/…) 
at NoProviderError.AbstractProviderError [as constructor]

如果相同的代码在 beta 中工作，是什么让它在 RC1 router-deprecated 中不工作？
