Build não gera o modulo de Lazy Loading do Home Component

Após os ajustes de app-routing.module e home.routing.module a página de login não é carregada e acusa o seguinte erro: find module './home/home.module.ts' Error: Cannot find module './home/home.module.ts'

e outro detalhe ao fazer o Build: não gerou o arquivo '0' como mencionado no video:

home.routing.module.ts

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

import { HomeComponent } from './home.component';
import { AuthGuard } from '../core/auth/auth.guard';

const routes: Routes = [

    ]
  },
];

export class HomeRoutingModule { }

 {

 }

];

@NgModule({

  exports: [RouterModule]
})
export class AppRoutingModule { }

Onde eu errei?
