假设.ANY建议您已经运行了以下命令;

ionic plugin add cordova-plugin-geolocation 
npm install --save @ionic-native/geolocation 
ionic plugin add cordova-plugin-mauron85-background-geolocation 
npm install --save @ionic-native/background-geolocation 

尝试导入插件如下：

import { BackgroundGeolocation } from '@ionic-native/background-geolocation'; 
import { Geolocation, Geoposition } from '@ionic-native/geolocation';
