类型“typeof File”离子打字稿上不存在属性“moveFile”

Question

不确定出了什么问题，但是当我尝试使用来自 @ionic-native 的文件时，我收到错误消息“'typeof File' 类型上不存在属性 'moveFile'”。包子是在cmets中询问后添加的

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

constructor(public navCtrl: NavController, public toastCtrl: ToastController) {
  //  this.checkPermissions();
  }
  fileName = fileName.split("/").pop();
    File.moveFile(currentPath, fileName, externalStoragePath, fileName).then(_ => {
    this.toastCtrl.create(

package.json 应 cmets 的要求

您正在使用ionic-native 3.x。

您需要在构造函数中注入File 并使用该对象。 ionic-native 2.x 中存在类中的静态函数。

constructor(public navCtrl: NavController, public toastCtrl: ToastController,
     public file:File) {
  //  this.checkPermissions();
  }
  fileName = fileName.split("/").pop();
    this.file.moveFile(currentPath, fileName, externalStoragePath, fileName).then(_ => {
    this.toastCtrl.create(

您还需要在 app.module.ts 中将File 设置为提供程序。

@NgModule({
 //..
 providers: [..,File,..]
  })
