1. 使用angular cli创建组件

ng g component navbar
ng g component stars
ng g component product
ng g component search
ng g component carousel
ng g component footer

都能看到如下这样，就是生成成功了

CREATE src/app/stars/stars.component.html (24 bytes)
CREATE src/app/stars/stars.component.spec.ts (621 bytes)
CREATE src/app/stars/stars.component.ts (265 bytes)
CREATE src/app/stars/stars.component.css (0 bytes)
UPDATE src/app/app.module.ts (1251 bytes)

2. 在app.component.html中构建基础布局框架

<app-navbar></app-navbar>
<div class="container">
  <div class="row">
    <div class="col-md-3">
      <app-search></app-search>
    </div>
    <div class="col-md-9">
      <div class="row">
          <app-carousel></app-carousel>
      </div>
      <div class="row">
          <app-product></app-product>
      </div>
    </div>
  </div>
</div>
<app-footer></app-footer>
