我想使用cordova 文件传输插件 https://cordova.apache.org/docs/en/latest/reference/cordova-plugin-file-transfer/。我通过使用它Ionic-Native 传输模块 https://ionicframework.com/docs/v2/native/transfer/.
该应用程序将无法运行，因为文件传输插件和文件插件 https://cordova.apache.org/docs/en/latest/reference/cordova-plugin-file/:
transpile started ...
typescript: plugins/cordova-plugin-file-transfer/types/index.d.ts, line: 9
Cannot find type definition file for 'cordova-plugin-file'.
L8: * @param server URL of the server to receive the file, as encoded by encodeURI().
L9: * @param successCallback A callback that is passed a FileUploadResult object.
L10: * @param errorCallback A callback that executes if an error occurs retrieving the FileUploadResult.
我安装了@types/cordova-plugin-file通过 npm，但由于两个 cordova-plugin-file 包中存在重复的标识符，该应用程序将无法运行：
transpile started ...
typescript: node_modules/@types/cordova-plugin-file/index.d.ts, line: 376
Duplicate identifier 'PERSISTENT'.
typescript: node_modules/@types/cordova-plugin-file/index.d.ts, line: 377
Duplicate identifier 'TEMPORARY'.
typescript: plugins/cordova-plugin-file/types/index.d.ts, line: 376
Duplicate identifier 'PERSISTENT'.
typescript: plugins/cordova-plugin-file/types/index.d.ts, line: 377
Duplicate identifier 'TEMPORARY'.
这里正确的方法是什么？
如前所述，cordova-plugin-file-transfer 中的输入似乎不正确。
它应该是一个外部模块，但它目前是一个脚本文件（直接从DefiniteTyped复制）。
另一方面，由于 cordova-plugin-file 已经包含自己的类型，因此您不需要安装 @types/cordova-plugin-file 。
我也经历过这个问题。
然而我能够解决办法以下操作的问题：
Setup :
```
Your system information:
Cordova CLI: 6.5.0

解决方法步骤：
- 删除平台
- 删除 Cordova 插件
- 重建项目
- 添加平台
- 删除 cordova-plugin-file-transfer 插件
-
重建ios项目
```
