上述问题通过删除节点模块得到解决

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): An argument for 'opts' is not provided

 viewchild @ViewChild('maincontent') mainContent: any; An argument for 'opts' was not provided.  error TS2554: Expected 2 arguments, but got 1 in v8

打字稿

 export class ViewchildexampleComponent implements OnInit {
 @ViewChild('maincontent') mainContent: any;

正如 SiddAjmera 建议的删除node_modules文件夹并运行npm install似乎可以解决问题。解决了我的atlist
