如何使用EventEmitter将功能传递给子组件？

我有一个父子组件设置，在子元素中的（轻击）事件上，我需要调用父方法。我正在尝试eventEmmiter，但遇到此错误：

错误：com.tns.NativeScriptException：无法找到模块：“事件”，相对于：app / tns_modules /

Parent.component.html

<app-header (thisEvent)="navigate($event)"></app-header>

Parent.component.ts

import { Component } from "@angular/core";
@Component({
  moduleId: module.id,
  selector: "app-main",
  templateUrl: "./parent.component.html",
  styleUrls: ["./parent.component.css"]
})
export class ParentComponent {
naviagte(args){
this.router.navigate(["/"]);
}
}

Child.component.html：

<Button text="Tap" class="btn btn-primary" (tap)="onTap($event)"></label>

Child.component.ts：

import { Component, Input, Output } from "@angular/core";
import { EventEmitter } from "events";
@Component({
  selector: "app-header",
  moduleId: module.id,
  templateUrl: "./child.component.html",
  styleUrls: ["./child.component.css"]
})
export class ChildComponent {
  @Output()
  thisEvent= new EventEmitter();
  navigate(args) {
    this.thisEvent.emit(null);
  }
}
