[angular] 컴포넌트는 2 개 모듈 선언의 일부입니다.

ionic 2 앱을 구축하려고합니다. ionic serve로 브라우저에서 앱을 시도하거나 에뮬레이터에서 실행하면 모든 것이 잘 작동합니다.

하지만 오류가 발생할 때마다 빌드하려고하면

ionic-app-script tast: "build"
Error Type AddEvent in "PATH"/add.event.ts is part of the declarations of 2 modules: AppModule in "PATH"/app.modules.ts and AddEvent in "PATH"/add-event.module.ts.
Please consider moving AddEvent in "PATH"/add-event.ts to a higher module that imports AppModule in "PATH"/app.module.ts and AddEventModule.
You can also creat a new NgModule that exports and includes AddEvent then import that NgModule in AppModule and AddEventModule

내 AppModule은

import { NgModule, ErrorHandler } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { IonicApp, IonicModule, IonicErrorHandler } from 'ionic-angular';
import { AngularFireModule } from 'angularfire2';
import { MyApp } from './app.component';
import { Eventdata } from '../providers/eventdata';
import { AuthProvider } from '../providers/auth-provider';
import { HttpModule } from '@angular/http';

import { HomePage } from '../pages/home/home';
import { Login } from '../pages/login/login';
import { Register } from '../pages/register/register';
import { AddEvent } from '../pages/add-event/add-event';
import { EventDetails } from '../pages/event-details/event-details';

import { StatusBar } from '@ionic-native/status-bar';
import { SplashScreen } from '@ionic-native/splash-screen';


@NgModule({
  declarations: [
    MyApp,
    HomePage,
    Login,
    Register,
    AddEvent,
    EventDetails

  ],
  imports: [
    BrowserModule,
    IonicModule.forRoot(MyApp),
    HttpModule,
    AngularFireModule.initializeApp(config)
  ],
  bootstrap: [IonicApp],
  entryComponents: [
    MyApp,
    HomePage,
    Login,
    Register,
    AddEvent,
    EventDetails
  ],
  providers: [
    StatusBar,
    SplashScreen,
    {provide: ErrorHandler, useClass: IonicErrorHandler}, Eventdata, AuthProvider
  ]
})
export class AppModule {}

내 add-event.module.ts는

import { NgModule } from '@angular/core';
import { IonicPageModule } from 'ionic-angular';
import { AddEvent } from './add-event';

@NgModule({
  declarations: [
    AddEvent,
  ],
  imports: [
    IonicPageModule.forChild(AddEvent),
  ],
  exports: [
    AddEvent
  ]
})
export class AddEventModule {}

선언 중 하나를 제거해야한다는 것을 이해하지만 방법을 모르겠습니다.

AppModule에서 선언을 제거하면 ionic serve를 실행하는 동안 로그인 페이지를 찾을 수 없다는 오류가 발생합니다.
