将我的angular2 beta应用程序升级到RC1版本后，我的浏览器控制台日志中出现以下错误：

我真的不知道是什么导致这个，为什么以及如何。

希望有人可以帮忙解决这个问题，谢谢！

Answer 1

更换到新的路由器系统时遇到了同样的问题。在我引导应用程序的文件中，我没有调用正确的ROUTER_PROVIDER。它叫

import {ROUTER_PROVIDERS} from '@angular/router-deprecated';

而不是

import {ROUTER_PROVIDERS} from '@angular/router';

有太多的线要改变，难怪我跳过了一条。

Answer 2

发生此问题是因为您忘记在主要组件中注册提供商。

因此，您必须导入ROUTER_PROVIDER，然后必须在组件中注册它。

import { Routes, ROUTER_DIRECTIVES, ROUTER_PROVIDERS } from '@angular/router';
... other imports

@Component({
  moduleId: module.id,
  selector: 'app',
  templateUrl: 'app.component.html',
  styleUrls: ['app.component.css'],
  directives: [ROUTER_DIRECTIVES],
  providers: [ROUTER_PROVIDERS]
})

来自@Component的数组提供程序非常重要。
