Javascript 找不到模块"；cordova/exec“；在离子2中

我正在尝试用typescript开发一个项目，但为此我需要用javascript运行一个库，库的链接就是这样

当我试图用我的代码运行这个库时，ionic 2返回上面的错误。我每天都在尝试解决这个问题，并且已经通过了google中所有的集成javascript和typescript教程。有人能帮我管理这个图书馆吗

我的代码如下：

guarda-codigo.ts：

import { Component } from '@angular/core';
        import { NavController } from 'ionic-angular';
        import { GrabbaProxcard } from './com.grabba.cordova.plugin/www/grabba';

        declare var cordova: any;

        /*
          Generated class for the GuardaCodigo page.

          See http://ionicframework.com/docs/v2/components/#navigation for more info on
          Ionic pages and navigation.
        */
        @Component({
          selector: 'page-guarda-codigo',
          templateUrl: 'guarda-codigo.html'
        })
        export class GuardaCodigoPage {

          constructor(public nav: NavController) {
              function acessaGrabba(value: number){
              let proxcard = new GrabbaProxcard();
                proxcard.prototype.registerCallback();
              }
          }

          ionViewDidLoad() {
            console.log('ionViewDidLoad GuardaCodigoPage');
          }

        }

guarda-codigo.html：

<ion-header>
  <ion-navbar>
    <ion-title>GuardaCodigo</ion-title>
  </ion-navbar>

</ion-header>

<ion-content class="registration">
<ion-list>
    <ion-item>
      <ion-label> Codigo</ion-label>
      <ion-input type="text" name = "Codigo"></ion-input>
    </ion-item>
</ion-list>
  <button ion-button onclick="acessaGrabba(2)">Trigger</button>
</ion-content>
