        // handle error
        console.log('download EROR: ' + error);

在下载页面和提供商应用程序模块中导入的文件

File imported in download page and providers app module

推荐答案

Ionic 4在compairson到Ionic 3中使用了不同的导入路径.

Ionic 4 uses different import paths in compairson to Ionic 3.

import { FileTransfer, FileUploadOptions, FileTransferObject } from '@ionic-native/file-transfer/ngx';
import { File } from '@ionic-native/file/ngx';
