Angular 角6共享模块不工作

我正在创建一个angular 6应用程序，我需要一个任何页面或一些页面的共享标题，我包括这一点，但不工作。我怎么了？。发送登录url**时显示演示错误，此处出错**”

登录模块是

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { LoginComponent } from './login.component';
import { LoginRoutingModule } from './login-routing.module';
import { PrimeryHeaderModule } from '../share';
@NgModule({
  imports: [
    CommonModule, LoginRoutingModule,PrimeryHeaderModule
  ],
  declarations: [LoginComponent]
})
export class LoginModule { }

路由器模块是

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
const routes: Routes = [
    { path: 'login', loadChildren: './login/login.module#LoginModule'}
];

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

您需要在HeaderModule中导出

HeaderComponent

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

HeaderComponent

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';
import { AppComponent } from './app.component';
import { HelloComponent } from './hello.component';

// routing 
import { AppRoutingModule } from './app-routing.module';

@NgModule({
  imports:      [ BrowserModule, FormsModule, AppRoutingModule ],
  declarations: [ AppComponent, HelloComponent ],
  bootstrap:    [ AppComponent ]
})
export class AppModule { }

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

是的，谢谢你，兄弟。是的，谢谢你，兄弟。

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';
import { AppComponent } from './app.component';
import { HelloComponent } from './hello.component';

// routing 
import { AppRoutingModule } from './app-routing.module';

@NgModule({
  imports:      [ BrowserModule, FormsModule, AppRoutingModule ],
  declarations: [ AppComponent, HelloComponent ],
  bootstrap:    [ AppComponent ]
})
export class AppModule { }
