Miért nem tud az Ionic 4 Framwork apk-t létrehozni?

Szia, ionic cordova build android --prod --release ezt a parancsot használtam APK generálásához Ionic 4-ben, de ilyen hibát kapok

Ez a kód az app.module.ts fájlban, mivel a hiba csak itt látható.

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 { HomePage } from '../pages/home/home';
import { CategoryPage } from '../pages/category/category';
import { CustomPage } from '../pages/custom/custom';
import { NewstuffPage } from '../pages/newstuff/newstuff'
import { ChinesePage } from '../pages/chinese/chinese';
import { ItalianPage } from '../pages/italian/italian';
import { MexicanPage } from '../pages/mexican/mexican';

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

@NgModule({
  declarations: [
      MyApp
  ],
  imports: [
    BrowserModule,
    CategoryPage,
    HomePage,
     CustomPage,
     ChinesePage,
      ItalianPage,
       MexicanPage,
       NewstuffPage,
    IonicModule.forRoot(MyApp)
  ],
  bootstrap: [IonicApp],
  entryComponents: [
    MyApp,
    CategoryPage,
    HomePage,
     CustomPage,
     ChinesePage,
      ItalianPage,
       MexicanPage,
       NewstuffPage
  ],
  providers: [
    StatusBar,
    SplashScreen,
    {provide: ErrorHandler, useClass: IonicErrorHandler}
  ]
})
export class AppModule {}
