vue2踩坑之项目：Swiper轮播图使用

首先安装swiper插件

npm i swiper@5

安装出现错误：npm ERR

解决方法：npm 版本太高，切换一下就好了

如下代码运行后再重新 npm i

npm install [email protected] -g

引入Swiper

// 可以直接在组件里引入这个文件

//导入js

import Swiper from "swiper";

//引入css

import "swiper/css/swiper.min.css";

代码：

javascript 复制代码

//html结构
<template>
  <!-- 记得将swiper修改过来 -->
  <div class="swiper-container" id="swiperContainer">
    <div class="swiper-wrapper">
      <div class="swiper-slide" style="background-color: #0091FE;">
