    ![输入图片说明](https://static.oschina.net/uploads/img/201802/27191043_9xqf.jpg "在这里输入图片标题")
    主要是FormsModule 每一个module里面都引入
    import { NgModule } from '@angular/core';

    import { P404Component } from './404.component';
    import { P500Component } from './500.component';
    import { LoginComponent } from './login.component';
    import { RegisterComponent } from './register.component';
    // import { AppModule } from '../app.module';
    import { FormsModule} from "@angular/forms";
    import {CommonModule} from "@angular/common";

    // import { AppComponent } from '../app.component';

    import { PagesRoutingModule } from './pages-routing.module';

    @NgModule({
      imports: [ PagesRoutingModule ,FormsModule],
      declarations: [
      P404Component,
      P500Component,
      LoginComponent,
      RegisterComponent
      ],
      exports:[
        CommonModule,
        FormsModule,
      ]
    })
    export class PagesModule { }
