Typescript 财产'；移动文件'；不存在于类型'；文件类型'；离子字体

不确定是什么问题，但当我尝试使用@ionic native中的文件时，我收到错误“类型“typeof File”上不存在属性“moveFile”。在评论中询问后，添加了该软件包

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根据评论要求

您正在使用的是爱奥尼亚原生3.x

您需要插入构造函数并使用对象。类中的静态函数存在于

ionic native 2.x

中

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(

您还需要将

文件设置为app.module.ts中的提供者

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

show constructor code这对代码编辑器有效，但当我尝试执行ionic Service时，我收到：“无法解析（[object]），[？]的所有参数。”“这可能是另一个问题。。是同一条线吗？另外，cordova插件不适用于
ionic serve
使用emulator/DeviceId您在ngModule中将文件设置为提供程序？是的，我尝试过，但在emulator/device中使用ionic Servery后仍然出现相同的错误。。cordova插件在serve中不起作用
