Angular 6：功能模块之间的共享组件不起作用

ERROR Error: Uncaught (in promise): Error: Template parse errors: 'app-main-menu' is not a known element:

如果它有任何区别,HomeModule是一个路由延迟加载的模块.

我的代码：

SRC /应用程序/页/页共享/页-shared.module.ts

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { MainMenuComponent } from './main-menu/main-menu.component';

@NgModule({
  imports: [
    CommonModule
  ],declarations: [
    MainMenuComponent
  ],exports: [
    MainMenuComponent
  ]
})

export class PagesSharedModule { }

SRC /应用程序/页/页共享/主菜单/主menu.component.ts

import { Component,OnInit } from '@angular/core';

@Component({
  selector: 'app-main-menu',templateUrl: './main-menu.component.html',styleUrls: ['./main-menu.component.scss']
})
export class MainMenuComponent implements OnInit {
  constructor() { }
  ngOnInit() { }
}

SRC /应用/网页/家/ home.module.ts

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { HomeComponent } from './home.component';
import { HomeRoutingModule } from './home-routing.module';
import { PagesSharedModule } from 'src/app/pages/pages-shared/pages-shared.module';

@NgModule({
  imports: [
    CommonModule,HomeRoutingModule,PagesSharedModule
  ],declarations: [
    HomeComponent
  ]
})

export class HomeModule { }

SRC /应用/网页/家/ home.component.html

<app-main-menu></app-main-menu>

SRC /应用/网页/网页,routing.module.ts

...
{
  path: '',component: PagesComponent,children: [
    {
      path: '',pathMatch: 'full',loadChildren: './home/home.module#HomeModule'
    },{
      path: 'about',loadChildren: './content/content.module#ContentModule'
    },{ path: '**',component: PageNotFoundComponent }
  ]
},...

SRC /应用/网页/家庭/家庭routing.module.ts

{
  path: '',component: HomeComponent
}

我做错了什么？谢谢.
