当我尝试使用** Ionic build android --prod **进行构建时，不是已知财产

Question

我尝试使用 Ionic build android --prod 构建项目，但始终出现以下错误：

<events-list>组件在EventslistModule中声明：

   declarations: [
       EventsListComponent,
       NewestEventsComponent
   ],
   imports: [IonicModule, LoaderModule],
   exports: [
       EventsListComponent,
       NewestEventsComponent,
   ],
   schemas: [CUSTOM_ELEMENTS_SCHEMA, NO_ERRORS_SCHEMA]
})
export class EventsListModule {}

这是events-list.ts中的属性：

@Input() set eventChange(filteredEvents){
    this.filteredEvents = filteredEvents;

    if(this.initial == true){
        this.loadData();
    }
  };

  @Input() created:boolean = false;
  @Input() search:boolean = false;
  @Input() id:string;
  @Input() answered:boolean = false;
  @Input() fromCalender:boolean = true;
  @Input() status:number = 4;
  @Input() showMessages = true;

Ionic:

   Ionic CLI          : 5.4.4 (/usr/local/lib/node_modules/ionic)
   Ionic Framework    : ionic-angular 3.9.9
   @ionic/app-scripts : 3.2.4

Cordova:

   Cordova CLI       : 8.1.2 (cordova-lib@8.1.1)
   Cordova Platforms : android 8.1.0, browser 5.0.3, ios 5.0.1
   Cordova Plugins   : cordova-plugin-ionic-keyboard 2.1.3, cordova-plugin-ionic-webview 1.2.1, (and 30 other plugins)

Utility:

   cordova-res : not installed
   native-run  : 0.2.8 (update available: 0.3.0)

System:

   Android SDK Tools : 26.1.1 (/Users/leonardoprivat/Library/Android/sdk)
   ios-sim           : 8.0.2
   NodeJS            : v10.16.3 (/usr/local/bin/node)
   npm               : 6.9.0
   OS                : macOS Mojave
   Xcode             : Xcode 11.0 Build version 11A420a

当我在没有-prod 的情况下构建项目时，它会正常工作。

任何想法我如何解决这个问题？
