angular - Angular 6：在功能模块之间共享组件不起作用

问题描述

我创建了 2 个功能模块（PagesSharedModule& HomeModule）。
现在我正在尝试从PagesSharedModule组件的模板内部使用导出的组件，HomeModule我收到此错误：

ERROR Error: Uncaught (in promise): Error: Template parse errors: 'app-main-menu' is not a known element:
1. If 'app-main-menu' is an Angular component, then verify that it is part of this module.
2. If 'app-main-menu' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message. ("[ERROR
->]<app-main-menu></app-main-menu>"): ng:///HomeModule/HomeComponent.html@0:0 Error: Template parse errors: 'app-main-menu' is not a known element:
1. If 'app-main-menu' is an Angular component, then verify that it is part of this module.
2. If 'app-main-menu' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message. ("[ERROR

如果有什么不同，那HomeModule就是路由的延迟加载模块。

我的代码：

src/app/pages/pages-shared/pages-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/app/pages/pages-shared/main-menu/main-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/app/pages/home/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/app/pages/home/home.component.html

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

src/app/pages/pages-routing.module.ts

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

src/app/pages/home/home-routing.module.ts

{
  path: '',
  pathMatch: 'full',
  component: HomeComponent
}


我究竟做错了什么？
谢谢。

解决方案

更新：
难以置信！！！
我停止了 angular CLI 并再次提供服务，现在一切正常，代码没有任何变化。
把这个注释留在这里，以防其他人面临同样的问题......
