Question

我正在尝试将panel-tres更改为coincidencia，但是当我尝试执行此错误时

我没有成功尝试改变，可能是什么错误？

这个组件1

＆＃13;

import {
  Component,
  OnInit,
  Input
} from '@angular/core';

@Component({
  selector: 'app-panel-tres',
  templateUrl: './panel-tres.component.html',
  styleUrls: ['./panel-tres.component.css']
})
export class PanelTresComponent implements OnInit {
  tituloGestionTelefonica: string;


  constructor() {

    this.tituloGestionTelefonica = "Titulo1";
}

  ngOnInit() {

  }

}

＆＃13;

这是组件2

＆＃13;

import {
  Component,
  OnInit,
  Input
} from '@angular/core';
import {
  PanelTresComponent
} from '../../panel-tres/panel-tres.component'

@Component({
  selector: 'app-coincidencia',
  templateUrl: './coincidencia.component.html',
  styleUrls: ['./coincidencia.component.css']
})
export class CoincidenciaComponent implements OnInit {
  @Input()
  panelTresComponent: PanelTresComponent;

  constructor() {}

  ngOnInit() {}

}

＆＃13;

这是组件2的html

＆＃13;

<div class="small-6 columns">
  <span>{{panelTresComponent.tituloGestionTelefonica}}</span>
</div>

＆＃13;

这是错误

＆＃13;
