javascript - Angular 实例化类错误

Question

当我尝试在 Angular 4 中实例化一个类时，出现此错误:

提供的参数与调用目标的任何签名都不匹配

admin.component.ts:

import { Component } from '@angular/core';
import { Event } from '../event';

@Component({
  selector: 'app-admin',
  templateUrl: './admin.component.html',
})
export class AdminComponent {
  onSubmit() { 
    const event = new Event('foo', 'bar');
  }
}

event.ts:

export class Event {
    constructor(
        public event: string,
        public comments: string
    ) { }
}

根据各种 StackOverflow 答案，我尝试了不同的 event.ts 但它产生了相同的错误:

export class Event {
    event: string;
    readableDate: string;
    constructor(public event: string, public readableDate: string) {
        this.event = event;
        this.readableDate = readableDate;
    }
}

Answer 1

查看语句中的Event类

const event = new Event('foo', 'bar');

以及它指的是哪一个。它可能会与 Angular 或 Javascript 的 Event 类混淆。
