Can't bind to 'ngIf' since it isn't a known property of 'div'.

元素是 <div [ngIf]="isAuth" id="sidebar">

该组件是:

import SessionService from '../session/session.service';
 import { Component  } from '@angular/core';

@Component({
  providers: [],
  selector: 'navbar-left',
  styles: [require('./navbar-left.scss')],
  template: require('./navbar-left.html'),
})
export default class NavbarLeftComponent {

  public isAuth: boolean = false;

  constructor(private sessionService: SessionService) {
    this.isAuth = sessionService.sessionIsAuth();
  }

}

不确定我到底做错了什么？这是一个儿童组件.在父组件aka App组件中,ngif可以工作.角度RC5

我在客户端上有以下javascript

var NodeRSA = require('node-rsa');

var ClientSide = new NodeRSA({ b: 512 });
var privateKey = `-----BEGIN RSA PRIVATE KEY-----
