angular - 为什么我得到 "Cannot find name ' NgModule '"despite running "npm i @types/node --global”？

Question

尽管遵循此处的建议- TypeScript error in Angular2 code: Cannot find name 'module' ，我仍然收到此错误。我正在使用 Angular 5 和 npm 6.9.0。我正在尝试在这里完成本教程 -- https://medium.freecodecamp.org/learn-how-to-create-your-first-angular-app-in-20-min-146201d9b5a7 .

我在 ./src/app/app.component.ts 文件的顶部有这个

import { Component,trigger,animate,style,transition,keyframes } from '@angular/core';
import { FormsModule }   from '@angular/forms';

@NgModule({
  imports: [
             BrowserModule,
             FormsModule      //<----------make sure you have added this.
           ],
})

但是当我运行我的应用程序时出现错误

ERROR in src/app/app.component.ts(4,2): error TS2552: Cannot find name 'NgModule'. Did you mean 'module'?
src/app/app.component.ts(6,14): error TS2304: Cannot find name 'BrowserModule'.

我还需要做什么才能让 NgModule 得到认可？

Answer 1

这个错误，Cannot find name 'NgModule' , 是因为没有导入 NgModule来自 @angular/core .将其添加到第一行将解决问题。
