Angular组件无法显示，仅展示src目录下的Index.HTML

开发Angular项目过程中，组件突然停止显示，页面仅展示src目录下的Index.HTML文件，而非app-component。已尝试多种解决方案但均无效。

关键文件内容 #

app.module.ts #

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { Punto1Component } from './components/punto1/punto1.component';
import { FormsModule } from '@angular/forms';

@NgModule({
  declarations: [
    AppComponent,
    Punto1Component
  ],
  imports: [
    BrowserModule,
    AppRoutingModule,
    FormsModule,
        
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Index.Html #

<!doctype html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <title>TpAngular</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></app-root>
</body>
</html>

app-component.html #

<app-punto1></app-punto1>

punto1.component.ts #

import { Component, OnInit } from '@angular/core';
import {Producto} from 'src/app/models/producto'
declare var window:any;
@Component({
  selector: 'app-punto1',
  templateUrl: './punto1.component.html',
  styleUrls: ['./punto1.component.css']
})
export class Punto1Component implements OnInit{
ngOninit(){ }
}
