sqlitePlugin错误而在离子2

Question

I'm trying to implement this simple example given in ionic 2 doc: http://ionicframework.com/docs/v2/native/sqlite/

使用SQLite我想，例如在MAC（执行离子项目的'www\test.sqlite'文件夹下放置在分贝的查询）和i得到两者上的浏览器和iOS模拟器此错误（没有按”在设备上要么吨工作）：

的ReferenceError：sqlitePlugin没有定义

我已经加入科尔多瓦-源码存储插件离子项目。

代码：

constructor(public navCtrl: NavController, public platform: Platform, 
       public pps: ProdPerfService){ 
     platform.ready().then((readySource) => { 
      pps.getSummary(); //pps is a provider named ProdPerfService 
     }); 
    } 

//ProdPerfService: 
import { Injectable } from '@angular/core'; 
import { SQLite } from 'ionic-native'; 

@Injectable() 
export class ProdPerfService { 
    constructor(){ 

    } 

    getSummary(){ 
     let db = new SQLite(); 
     db.openDatabase({ 
      name: 'test.sqlite', 
      location: 'default' // the location field is required 
     }).then(() => { 
      db.executeSql('select * from summary', {}).then(() => { 
       alert('result'); 

     }, (err) => { 
      console.error('Unable to execute sql: ', err); 
      alert('err'); 
     }) 
     }, (err) => { 
      console.error('Unable to open database: ', err); 
      alert(err); 
     }); 
    } 

}

尝试移动你的逻辑构造出来的。

ionViewDidLoad(){ 
    this.platform.ready().then((readySource) => { 
     this.pps.getSummary(); //pps is a provider named ProdPerfService 
    }); 
}
