Question

我使用material2和anular2处理了应用程序。我有这个错误“this._appRef.registerChangeDetector不是一个函数”。

小吃吧-material.html：

<button md-button (click)="openSnackBar()">Trigger Snackbar</button>

TS功能：

import { Component} from '@angular/core';
import {MdSnackBar} from '@angular/material';

@Component({
   templateUrl:'snackbar-material.html',
 })
export class SnackbarOverviewComponent{
 constructor(
    public snackBar: MdSnackBar) {}
openSnackBar() {
this.snackBar.open("Showing Snack", "Yayyy!");    
}
}

错误：
