Ionic v4 lazy loading not working after migrating from v3

Ionic Framework
1

I had working lazy loading in v3 and after updating with v4 it stopped working.
What i have is:

Ionic:

   ionic (Ionic CLI)  : 4.10.2
   Ionic Framework    : ionic-angular 3.9.3
   @ionic/app-scripts : 3.2.2

Cordova:

   cordova (Cordova CLI) : 8.1.2 (cordova-lib@8.1.1)
   Cordova Platforms     : android 6.3.0, ios 4.5.5
   Cordova Plugins       : cordova-plugin-ionic-keyboard 2.1.3, cordova-plugin-ionic-webview 1.2.1, (and 18 other plugins)

System:

   NodeJS : v9.8.0 (/usr/local/bin/node)
   npm    : 5.6.0
   OS     : macOS High Sierra
   Xcode  : Xcode 9.2 Build version 9C40b

with angular/core@5.2.11

i made app-routing.module.ts:

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

const routes: Routes = [
  { path: '', redirectTo: '/home', pathMatch: 'full' },
  { path: 'home', loadChildren: '../pages/home/home.module#HomePageModule'}
];
@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule]
})
export class AppRoutingModule {

}

app.module.ts looks:

import { AppRoutingModule } from '../app/app-routing.module';
...
imports: [
 RouterModule,
  CommonModule,
  AppRoutingModule,
...

home.module.ts is:

import { NgModule } from '@angular/core';
import { HomePage } from './home';
import { TranslateModule } from '@ngx-translate/core';
import { Routes, RouterModule } from '@angular/router';
import { IonicModule } from 'ionic-angular';
import { CommonModule } from '@angular/common';

const routes: Routes = [
  { path: '', component: HomePage }
];

@NgModule({
  declarations: [HomePage],
  imports: [
    IonicModule,
    CommonModule,
    RouterModule.forChild(routes),
    TranslateModule.forChild()
  ],
  exports: [RouterModule]
})
export class HomePageModule { }

app.html:

<ion-app>
    <ion-router-outlet></ion-router-outlet> 
</ion-app>

app.component.ts:

...
@Component( {
    templateUrl: 'app.html'
} )
...
this.router.navigateByUrl('/home');

With this code i am getting :

 Templete parse errors: "ion-router-outlet" is not a known element: 1. If "ion-router-outlet" is an Angular component, then verify that it is part of this module. ...

if i use “router-outlet” (without )i have this error :

Uncaught (in promise). Error: Cannot find module '../pages/home/home.module'. Error: Cannot find module '../pages/home/home.module' at ...

Unfortunately i cant find any proper guide how to migrate the lazy loading
