Javascript 基本角度组件不显示在浏览器中,javascript,angular,angular8,Javascript,Angular,Angular8,我刚刚运行了ngserve-o，只看到我刚刚开始修改的angular应用程序中显示的index.html文件。目前，该页面只是向您问好： // index.html <!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <title>Appclient</title> <base href="/"> <meta nam

我刚刚运行了

ngserve-o

，只看到我刚刚开始修改的angular应用程序中显示的

index.html

文件。目前，该页面只是向您问好：

// index.html
<!doctype html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <title>Appclient</title>
  <base href="/">

  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="icon" type="image/x-icon" href="favicon.ico">
</head>
<body>
  <app-root>hello</app-root>
</body>
</html>

我不确定我错过了什么

控制台错误为：

ReferenceError: global is not defined

index.js:43 第18页

您需要在

app.module.ts

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';
import { RouterModule, Routes } from '@angular/router';

import { AppComponent } from './app.component';
import { HelloComponent } from './hello.component';

const routes: Routes = [
  { path: 'hello', component: HelloComponent }
];

@NgModule({
  imports:      [ BrowserModule, FormsModule, RouterModule.forRoot(routes) ],
  exports:      [ RouterModule ],
  declarations: [ AppComponent, HelloComponent ],
  bootstrap:    [ AppComponent ]
})
export class AppModule { }

和

用于设置项目我确实设置了它，但当我开始添加内容时，它出错了浏览器控制台中显示的错误是什么？请不要错过检查控制台！看看这个
ReferenceError: global is not defined

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';
import { RouterModule, Routes } from '@angular/router';

import { AppComponent } from './app.component';
import { HelloComponent } from './hello.component';

const routes: Routes = [
  { path: 'hello', component: HelloComponent }
];

@NgModule({
  imports:      [ BrowserModule, FormsModule, RouterModule.forRoot(routes) ],
