我在Angular 2 （alpha版本49）中有这样的组件：
import {RouteConfig, ROUTER_DIRECTIVES, ROUTER_PROVIDERS,
LocationStrategy, HashLocationStrategy} from 'angular2/router';
@RouteConfig([
{path: '/DeleteProduct', as: 'DeleteProduct', component: DeleteProduct}
])
@Component({
selector: 'app'
})
@View({
directives: [ROUTER_DIRECTIVES],
template: `
<div>
<nav class="navbar navbar-default">
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<ul class="nav navbar-nav navbar-right">
<li><a [router-link]="['/DeleteProduct']">Add/Delete</a></li>
</ul>
</div>
</div>
</nav>
<div>
<router-outlet></router-outlet>
</div>
</div>
`
})
export class App {
}
工作得非常好。今天我将角度版本升级为 2.0.0-beta.0 。现在上面的代码失败了消息：
Can't bind to 'router-link' since it isn't a known native property ("collapse-1">

我犯错误的地方？ Changelog对此没有任何说法。
答案 0 :(得分：7)
路由器链接已重命名为routerLink，作为删除＆＃39; - ＆＃39;的一部分。基于语法。
我在这里有一个工作样本：http://www.syntaxsuccess.com/viewarticle/routing-in-angular-2.0

这个（ camelCase ）突破变化的链接：
Angular模板现在
case-sensitive并使用camelCase代替kebab-case (dash-case)在：
<p *ng-if="cond"> <my-cmp [my-prop]="exp"> <my-cmp (my-event)="action()"> <my-cmp [(my-prop)]="prop"> <input #my-input> <template ng-for #my-item [ng-for-of]=items #my-index="index">后：
<p *ngIf="cond"> <my-cmp [myProp]="exp"> <my-cmp (myEvent)="action()"> <my-cmp [(myProp)]="prop"> <input #myInput>`, <template ngFor="#myItem" [ngForOf]=items #myIndex="index">
和Observables问题的链接
从Observable重新导出angular2/core否在
import {Observable} from 'angular2/core'在
import {Observable} from 'rxjs/Observable';
