错误

src / app / custom-filterdt / custom-filterdt.component.ts（11,4）中的错误：错误TS2554：需要2个参数，但得到1个。

打字稿代码

SwiftUI

代码错误

 import { Component, OnInit, OnDestroy, ViewChild } from '@angular/core';
 import { DataTableDirective } from 'angular-datatables';
  @Component({
    selector: 'app-custom-filterdt',
    templateUrl: './custom-filterdt.component.html',
    styleUrls: ['./custom-filterdt.component.css']
    })

错误消息

导入组件模块'../../../node_modules/@angular/core/core“'没有导出的成员'Component'.ts（230

ng版本

import { Component, OnInit, OnDestroy, ViewChild } from '@angular/core';

最欢迎任何帮助

以上问题可通过删除节点模块来解决

但是在这个新错误之后

预期2个参数，但得到1.ts（2554） core.d.ts（8064，47）：未提供“ opts”的参数

正如SiddAjmera建议删除node_modules文件夹并运行npm install似乎可以解决此问题。解决了我的atlist

更新Angular 8.0后模块没有导出的成员Component
