loadChildren can't find module (lazy loading modules)

Question

I'm trying to implement lazy loading modules, but the error appears. My proest uses System.js, maybe I'm wrong to point out the way, how is it calculated?

My app.module.ts:

import { NgModule } from '@angular/core';
imports ...

const APP_ROUTES: Routes = [
    { path: 'user', loadChildren: 'build/app/profile/user/user.module#UserModule' },
    { path: '', redirectTo: 'login', pathMatch: 'full' }
];

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

My user.module.ts:

import { NgModule } from '@angular/core';
imports...

@NgModule({
  imports: [
     CommonModule,
     FormsModule,
     UserRouterModule
  ],
  declarations: [
      UserComponent,
      UserInfoComponent,
      UserEditPasswordComponent
  ],
  exports: [],
  providers: [
      AuthService,
      UserGuard,
      UserService
  ]
  })

  export class UserModule { }

My user-router.module.ts:

import { Routes } from '@angular/router';
imports ...

export const USER_ROUTES: Routes = [
    { path: '', component: UserInfoComponent, pathMatch: 'full' },
    { path: 'edit', component: UserEditPasswordComponent },
    { path: 'candidates', component: CandidateListComponent },
    { path: 'add-candidate', component: CandidateAddComponent },
    { path: 'candidates/:id/edit', component: CandidateEditComponent }
];

@NgModule({
   imports: [RouterModule.forChild(USER_ROUTES)],
   exports: [RouterModule]
})
export class UserRouterModule {}
