我試圖用NG2-QR碼在我的測試ionic2的應用程序，但是這從來沒有發現的指令，按照ionic serve輸出：Import指令 - NG2-QR碼

我按照readme在GitHub上做：
npm install ng2-qrcode
創建具有成分標註A類：
import { Component } from '@angular/core';
import { NavController, NavParams } from 'ionic-angular';
import {QRCodeComponent} from 'ng2-qrcode'
@Component({
templateUrl: 'build/pages/page1/page1.html',
directives: [QRCodeComponent],
})
export class Page1
{
constructor(private navCtrl: NavController) { }
}
，放在模板構建/頁/第1頁/ page1.html標籤：
<qrcode qrdata="'My QR code data string'" size="256" level="'M'"></qrcode>
但我發現了這個錯誤，什麼是錯的？很難找到Ionic2解釋或文件，我非常喜歡Ionic2和打字稿。
