angular - Cannot determine the module for class X in X.ts! Add X to the NgModule to fix it error in ionic2

I am facing an issue when I try to build my app using the following command :

ionic cordova run android --prod --release

Everything runs fine if I run the command as below:

ionic cordova run android

Cannot determine the module for class RemoveUnderscorePipe in C:/test/src/utils/pipes/RemoveUnderscore.t s! Add RemoveUnderscorePipe to the NgModule to fix it.

but I have added all my pages and pipes to app.module.ts as below :

// Imports

// The translate loader needs to know where to load i18n files
// in Ionic's static asset pipeline.
export function HttpLoaderFactory(http: Http) {
  return new TranslateHttpLoader(http, './assets/i18n/', '.json');
}


let pages:any = [
  MyApp,
  LoginPage,
  UserHomePage,
  SignupPage,
  AppHomePage,
  WelcomePage,
  ItemsPage,
  CartItemsPage,
  ProfilePage,
  MyOrdersPage,
  OrderDetailPage,
  ForgotPasswordPage,
  PincodePage,
  LogoutPage
];

let pipes = [RemoveUnderscorePipe];

export function declarations() {
  return pages.concat(pipes);
}

export function entryComponents() {
  return pages;
}

export function providers() {
  return [
    Api,
    ItemsService,
    UserService,
    ToastService,
    CartService,
    OrdersService,
    TokenService,
    Camera,
    GoogleMaps,
    SplashScreen,
    StatusBar,

    // Keep this to enable Ionic's runtime error handling during development
    {provide: ErrorHandler, useClass: IonicErrorHandler}
  ];
}


@NgModule({
  declarations: declarations(),
  imports: [
    BrowserModule,
    HttpModule,
    TranslateModule.forRoot({
      loader: {
        provide: TranslateLoader,
        useFactory: HttpLoaderFactory,
        deps: [Http]
      }
    }),
    IonicModule.forRoot(MyApp),
    IonicStorageModule.forRoot()
  ],
  bootstrap: [IonicApp],
  entryComponents: entryComponents(),
  providers: providers()
})
export class AppModule {
}

If u see my app.module.ts, I have added components and pipes to entrycomponents and declarations. Is there anything I am missing for production flag. How can I resolve this issue?

This could also be a filename casing problem. see https://github.com/angular/angular-cli/issues/10732
