Angular2句柄RouterOutlet：无法读取未定义的属性'_outlets'

Question

我使用angular2 v2.1.2，我想在加载页面之前检查路由器 登录后，如果用户输入网址/login，我的应用将导航至HomePage 如果我不login，我无法登录而无法访问任何页面。

我的问题是：如果我在一个浏览器上打开两个标签：
Tab one：登录，然后转到帐户页面 Tab two：登录，然后注销。然后返回tab one并重新加载page =＆gt;发生错误TypeError: Cannot read property '_outlets' of undefined 我该如何解决呢？

我有Routes

RouterModule.forRoot([
    {path: "login", component: LoginComponent},
    {path: "home", component: HomeComponent},
    {path: "accounts", component: AccountsComponent},
    {path: '', redirectTo: '/login', pathMatch: 'full'},
    {path: '**', component: HomeComponent}
]);

LoggedInRouterOutlet指令

import { Directive, ComponentRef, ResolvedReflectiveProvider, Injectable, ComponentFactoryResolver, Injector } from '@angular/core';
import { Router, RouterOutlet, RouterOutletMap, ActivatedRoute } from '@angular/router';

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

export class LoggedInRouterOutlet extends RouterOutlet {
    activate(activatedRoute: ActivatedRoute, loadedResolver: ComponentFactoryResolver, loadedInjector: Injector, providers: ResolvedReflectiveProvider[], outletMap: RouterOutletMap) {
        let isLogin = Storage.checkLogin(),
            loginComponents = ["login", "chooseAccount"],
            isPublic = activatedRoute.data.value.isPublic;

        if (isLogin) {
            if (_.includes(loginComponents, path)) {
                //navigate to HomePage if enter /login 
                location.href = '#/home';
            } else {
                return super.activate(activatedRoute, loadedResolver, loadedInjector, providers, outletMap);
            }
        } else {
            if (!_.includes(loginComponents, path)) {
                //navigate to LoginPage if enter /home, ...
                location.href = '#/login';
            } else {
                return super.activate(activatedRoute, loadedResolver, loadedInjector, providers, outletMap);
            }
       }
   }
}
