走马灯添加图片

html：

<el-carousel indicator-position="outside" height="170px">
        <el-carousel-item v-for="(item, idx) in carouselList" :key="idx">
          <img :src="item.src">
        </el-carousel-item>
      </el-carousel>

script:

data() {
    return {
      maintenanceBg: maintenanceBg,
      carouselList: [
        {src: maintenanceBg},
        {src: maintenanceBg},
        {src: maintenanceBg},
        {src: maintenanceBg},
      ]
    }
  }

　　一定要手动在script中引入图片：

import maintenanceBg from '../static/img/carousel.png'
