在离子本机中找不到FilePath

Question

我已经安装了以下插件：

ionic plugin add cordova-plugin-camera
ionic plugin add cordova-plugin-file
ionic plugin add cordova-plugin-file-transfer
ionic plugin add cordova-plugin-filepath

当我运行离子生成时，似乎找不到FilePath。

我的.ts文件中有以下导入语句

import { Camera, File, Transfer, FilePath } from 'ionic-native';

但是FilePath没有在离子本机中定义。

我正在使用Ionic 2版本：2.1.13和Cordova版本：6.4.0

我收到以下错误：

Answer 1

删除.tmp（/Users/cnadig-cc/workspace/ionic/tracks-driver/.tmp）和node_modules，然后再次运行npm install。
