以上为错误提示

我的Appmodules

    import { NgModule, ErrorHandler } from '@angular/core';
    import { BrowserModule } from '@angular/platform-browser';
    import { IonicApp, IonicModule, IonicErrorHandler } from 'ionic-angular';
    import { MyApp } from './app.component';
    import { AboutPage } from '../pages/about/about';
    import { ContactPage } from '../pages/contact/contact';
    import { HomePage } from '../pages/home/home';
    import { TabsPage } from '../pages/tabs/tabs';
    import { AppComponent }  from './app.component';
    import { StatusBar } from '@ionic-native/status-bar';
    import { SplashScreen } from '@ionic-native/splash-screen';

    @NgModule({
      declarations: [
        MyApp,
        AboutPage,
        ContactPage,
        HomePage,
        TabsPage,
        AppComponent,
      ],
      imports: [
        BrowserModule,
        IonicModule.forRoot(MyApp)
      ],
      bootstrap: [IonicApp],
      entryComponents: [
        MyApp,
        AboutPage,
        ContactPage,
        HomePage,
        TabsPage
      ],
      providers: [
        StatusBar,
        SplashScreen,
        {provide: ErrorHandler, useClass: IonicErrorHandler}
      ]
    })
    export class AppModule {}
    
    我的app.component.ts
    
    import {Component} from '@angular/core';
import {Platform} from 'ionic-angular';
import {StatusBar} from '@ionic-native/status-bar';
import {SplashScreen} from '@ionic-native/splash-screen';
import {TabsPage} from '../pages/tabs/tabs';




@Component({
  templateUrl: 'app.html'
})
export class AppComponent{
    
}
export class MyApp {
  rootPage: any = TabsPage;
  constructor(platform: Platform, statusBar: StatusBar, splashScreen: SplashScreen) {
    platform.ready().then(() => {
      // Okay, so the platform is ready and our plugins are available.
      // Here you can do any higher level native things you might need.
      statusBar.styleDefault();
      splashScreen.hide();
    });
  }
}

@Component({
templateUrl: 'app.html'
})
这里一看就少声明的，你新建模块最好用命令去建
