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 ionic build 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 ionic-native 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：
