ionic geolocation plugin error: "No provider for Geolocation"

Question

I'm trying to use geolocation in my ionic2 hello world project, and I add the ionic plugin "Geolocation" following the instruction on the official site.

I've run these two commands:

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

And this is my home.ts:

import { Component } from '@angular/core'; import {Geolocation} from '@ionic-native/geolocation' import { NavController } from 'ionic-angular';  @Component({   selector: 'page-home',   templateUrl: 'home.html' }) export class HomePage {   map:any=null;   geoInfo:any={       resp:'',       data:''   };    constructor(       public navCtrl: NavController,       private geolocation: Geolocation   ) {    }    test(){       this.geolocation.getCurrentPosition().then((resp) => {           this.geoInfo.resp=JSON.stringify(resp);           // resp.coords.latitude           // resp.coords.longitude       }).catch((error) => {           console.log('Error getting location', error);           this.geoInfo.resp='Error getting location';       });        let watch = this.geolocation.watchPosition();       watch.subscribe((data) => {           this.geoInfo.data=JSON.stringify(data);           // data can be a set of coordinates, or an error (if an error occurred).           // data.coords.latitude           // data.coords.longitude       });    }  } 

However, I got the following error in my chrome's console:

EXCEPTION: Error in ./TabsPage class TabsPage - inline template:0:0 caused by: No provider for Geolocation! error_handler.js:56ORIGINAL EXCEPTION: No provider for Geolocation! 

At first I thought it was because I was debugging in browser, but then I got then same error in my Android phone.

So what does "No provider for Geolocation" mean and how should I use geolocation in my ionic2 project?

Thanks a lot!

You need to add the provider to the NgModule, i.e module.ts under providers,

providers: [   Geolocation ]
