I am getting an error and can't find why. Here is the error:

Does anyone know why the router is throwing this? I am using angular2 beta
here is my code:
import {Component} from 'angular2/core';
import { RouteConfig, ROUTER_DIRECTIVES } from 'angular2/router';
import {LoginComponent} from './pages/login/login.component';
import {DashboardComponent} from './pages/dashboard/dashboard.component';
@Component({
selector: 'app',
directives:[ROUTER_DIRECTIVES],
template:`
<div class="wrapper">
<router-outlet></router-outlet>
</div>`
})
@RouteConfig([
{ path: '/',redirectTo: '/dashboard' },
{ path: '/login',name:'login',component: LoginComponent },
{ path: '/dashboard',name:'dashboard',component: DashboardComponent,}
])
export class AppComponent {
}
https://angular.io/docs/ts/latest/guide/router.html
Add the base element just after the
<head>
tag. If theapp
folder is the application root, as it is for our application, set thehref
value exactly as shown here.
The <base href="/">
tells the Angular router what is the static part of the URL. The router then only modifies the remaining part of the URL.
<head>
<base href="/">
...
</head>
Alternatively add
>= Angular2 RC.6
import {APP_BASE_HREF} from '@angular/common';
@NgModule({
declarations: [AppComponent],
imports: [routing /* or RouterModule */],
providers: [{provide: APP_BASE_HREF, useValue : '/' }]
]);
in your bootstrap.
In older versions the imports had to be like
< Angular2 RC.6
import {APP_BASE_HREF} from '@angular/common';
bootstrap(AppComponent, [
ROUTER_PROVIDERS,
{provide: APP_BASE_HREF, useValue : '/' });
]);
< RC.0
import {provide} from 'angular2/core';
bootstrap(AppComponent, [
ROUTER_PROVIDERS,
provide(APP_BASE_HREF, {useValue : '/' });
]);
< beta.17
import {APP_BASE_HREF} from 'angular2/router';
>= beta.17
import {APP_BASE_HREF} from 'angular2/platform/common';
