angular – 如何在RC.1中使用新路由器时扩展RouterOutlet

例：

import { Directive } from '@angular/core';
import { Router,ROUTER_DIRECTIVES,RouterOutlet } from '@angular/router';


@Directive({
  selector: 'router-outlet'
})

export class RouterOutletDirective extends RouterOutlet {

}

错误：

@angular/router/index”‘ has no exported member ‘RouterOutlet’.

我做错了什么或者这是否与RC.1中的新路由器有关？

更新：

import { Directive,Attribute,ViewContainerRef,DynamicComponentLoader } from '@angular/core';
import { Router,Routes,RouterOutletMap } from '@angular/router';
import { RouterOutlet } from '@angular/router/src/directives/router_outlet';


@Directive({
  selector: 'router-outlet'
})
export class RouterOutletDirective extends RouterOutlet {

  constructor(parentOutletMap: RouterOutletMap,_location: ViewContainerRef,name: string) {
    super(parentOutletMap,_location,name);
    console.log( parentOutletMap );
  }


  activate() {
    console.log('Activate');
  }
}

所以它现在正在运行,但是RouterOutlet用红色加下划线,类型“any”不是构造函数类型,激活部分也不起作用.我错过了什么吗？
