Use angular router error on 2.2.0

Ionic Framework ionic-v3
1

when I use angular router to change the view,it makes an error at

NavControllerBase.prototype.getActive = function () {
    return this._views[this._views.length - 1];
};

this._views is null.
but It is fine at 2.1.0

here is my code:
navigate:

this.router.navigate(['/home']);

home.component.ts:

import { Component } from '@angular/core';
import { RecommendPage } from './recommend/recommend.component';

@Component({
  template: '<ion-nav [root]="rootPage"></ion-nav>'
})

export class HomeComponent {
  // First page to push onto the stack
  rootPage = RecommendPage;
}

I don’t believe use of the Angular router is supported with Ionic.

It is working very well, until I updated to 2.2.0 last night.

angular router code:

app-routing.module

import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';

const appRoutes: Routes = [
  {
    path: '',
    redirectTo: '/home',
    pathMatch: 'full'
  }
];

@NgModule({
  declarations: [
  ],
  imports: [
    RouterModule.forRoot(appRoutes),
  ],
  exports: [
    RouterModule
  ]
})
export class AppRoutingModule {}

home.module.ts

import { NgModule } from '@angular/core';
import { IonicModule } from 'ionic-angular';
import { RouterModule, Routes } from '@angular/router';

import { AuthGuard } from '../../services/auth.module';
import { HomeComponent } from './home.component';
import { RecommendPage } from './recommend/recommend.component';
import { FootNavModule } from '../foot/foot-nav.module';

import { HomeService } from './home.service';

const homeRoutes: Routes = [
  { path: 'home', component: HomeComponent, canActivate: [AuthGuard] }
];

@NgModule({
  declarations: [
    HomeComponent,
    RecommendPage
  ],
  imports: [
    FootNavModule,
    RouterModule.forChild(homeRoutes),
    IonicModule
  ],
  entryComponents: [
    HomeComponent,
    RecommendPage
  ],
  providers: [HomeService]
})
export class HomeModule {
  constructor() {
    console.log('init HomeModule');
  }
}
