Angular 2 CanActivate不起作用

Question

I'm trying to create route guard, read a few blogs and Angular 2 official documentation on it. But I still can't make it work.

Here's RouteGuard (I've removed logging logic to be sure that problem is in routing, not in authentication logic.):

import { Observable } from 'rxjs/Observable';
import { Injectable } from '@angular/core';
import { Router, CanActivate, CanActivateChild, ActivatedRouteSnapshot, RouterStateSnapshot } from '@angular/router';

@Injectable()
export class RouteGuard implements CanActivate {
  constructor() {
    var a = 5;
    console.log("RouterGuard called");
  }

  canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot) {
    console.log("RouterGuard called");
    return true;
  }
}

Here i have some routes:

import { RouteGuard } from './common/routeGuard';
import { ClassifiersComponent } from './components/classifiers/classifiers.component';
import { Routes } from '@angular/router';
import { HomeComponent } from './components/home/home.component';

export const routes: Routes = [
    { path: '', component: HomeComponent },
    { path: 'classifiers', component: ClassifiersComponent, canActivate: [RouteGuard] },
];

And then i pass them in bootstrapper method:

import { RouteGuard } from './app/common/routeGuard';
import { ClassifiersComponent } from './app/components/classifiers/classifiers.component';
import { HomeComponent } from './app/components/home/home.component';
import { routes } from './app/app.routes';

@NgModule({
    imports: [
        RouterModule.forRoot(routes)
    ],
    providers: [
        { provide: LocationStrategy, useClass: PathLocationStrategy },
        { provide: APP_BASE_HREF, useValue: '/' },
        RouteGuard
    ],
    declarations: [
        AppComponent,
        HomeComponent,
        ClassifiersComponent
    ],
    bootstrap: [AppComponent]
})
export class AppModule {}

I'm not sure what is wrong with this all, may be I'm missing something important. From debugging I can tell that it's hitting canActivate() breakpoint, but does not execute console.log, same goes for constructor.

EDIT: Other routes where there is not any route authentication works fine.

EDIT2: I'm using angular/core 2.2.0, angular/router 3.2.0

更新到角/核心2 3 2.0，角/路由器3.3 0.0解决了这个问题，我不知道为什么。
