Angular 未捕获引用错误:\未定义导入默认值;上完九年级之后

Angular 未捕获引用错误:\未定义导入默认值;上完九年级之后,angular,angular9,Angular,Angular9,跑步后 ng serve 在浏览器“开发人员工具”中,我看到以下错误: Uncaught ReferenceError: __importDefault is not defined at Module../src/app/home/home.component.ts (home.component.ts:5) at __webpack_require__ (bootstrap:79) at Module../src/app/app-routing.module.ts

跑步后

ng serve
在浏览器“开发人员工具”中,我看到以下错误:

Uncaught ReferenceError: __importDefault is not defined
    at Module../src/app/home/home.component.ts (home.component.ts:5)
    at __webpack_require__ (bootstrap:79)
    at Module../src/app/app-routing.module.ts (main.js:98)

在my home.component.ts中,我有以下内容:

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

@Component({
  selector: 'miles-home',
  templateUrl: './home.component.html',
  styleUrls: ['./home.component.scss']
})
export class HomeComponent implements OnInit {

  constructor() { }

  ngOnInit() {
  }

}
这是我的设置:

第5行只是一个模板URL,所以不确定它在抱怨什么…

我最后在终端上运行了这个,这里有个神奇之处:

npm install --save-dev @angular-devkit/build-angular@latest

由于某种原因,它找不到模板吗?您是从最新的v8.x>9版本开始的,还是跳转了一个版本?请检查此项我已通过ng version命令添加了我的环境设置。我阅读了链接,但没有找到任何有帮助的解决方案@NadeemShaikh@mwilson我是按照这个指南一步一步地做的,这可能是因为
@angular devkit/architect
仍然指向angular 8而不是anngular 9?@AniruddhaDas!
