效果：

angular :13.1.0

swiper:8.4.7

看方法直接到最后

下面是一些坑：

搜angular swiper 结果是Swiper Angular Components (swiperjs.com)

照着引入，发现啥效果都没有 

网上的方法是在angular.json 的style[]里添加

有了部分样式 1.5张的预览，但是分页没有了。 

最后去油管学习了

  imports: [
    BrowserModule,
    AppRoutingModule,
    SwiperModule

2.app.component.html

<swiper
