我在下面缺少什么？我正在尝试在 Ionic 2 中使用 cordova-camera-plugins 和 ionic native，但在 ionic serve 后我收到以下运行时错误：“无法解析主页的所有参数：（[object Object]，[object Object]， [对象对象]，[对象对象]，？）。”

主页.ts

import { Component, Injectable } from '@angular/core';
import { NavController } from 'ionic-angular';
import { ToastController } from 'ionic-angular';
// import { File } from '@ionic-native/file';
import { Diagnostic } from '@ionic-native/diagnostic';
import { CameraPreview, CameraPreviewOptions, CameraPreviewDimensions} from '@ionic-native/camera-preview';
declare var cordova: any;

@Component({
  selector: 'page-home',
  templateUrl: 'home.html',

})

@Injectable()
export class HomePage {

  constructor(
    private navCtrl: NavController,
    private toastCtrl: ToastController,
    // public file:File,
    public diagnostic:Diagnostic,
    public cameraPreview: CameraPreview,
    public previewRect: CameraPreviewOptions
  ) {  this.checkPermissions(); }

app.module.ts

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 { Diagnostic } from '@ionic-native/diagnostic';


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

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

我曾经遇到同样的错误，现在它已修复。“无法解析主页的所有参数：([object Object], [object Object], [object Object], [object Object], ?)。”。

这 ”？” 可能意味着无法识别或其他什么，因此请尝试在构造函数中删除一些参数并将它们声明为普通数据成员（在构造函数上方）。例如，“public previewRect: CameraPreviewOptions”。
