测试了好多次，要么不显示图片，要么只显示图片的url，解决方法就是用require url来表示：
<div><el-carousel :interval="5000" arrow="always" style="height:450px"><el-carousel-item v-for="item in arraye" :key="item" style="height:450px"><img v-bind:src="item.url" alt=""><!--<img src="../../assets/images/juren9.jpg" alt="">--><!--<img src="../../assets/images/juren12.jpg" alt="">--><!--<img src="../../assets/images/juren13.jpg" alt="">--><!--<img src="../../assets/images/juren14.jpg" alt="">--><!--<img src="../../assets/images/juren15.jpg" alt="">--><!--<img src="../../assets/images/juren16.jpg" alt="">--></el-carousel-item></el-carousel></div>
return {arraye:[{url:require('../../assets/images/juren9.jpg')},{url:require('../../assets/images/juren12.jpg')},{url:require('../../assets/images/juren13.jpg')},{url:require('../../assets/images/juren14.jpg')},{url:require('../../assets/images/juren15.jpg')},{url:require('../../assets/images/juren16.jpg')},// "../../assets/images/juren9.jpg",// "../../assets/images/juren12.jpg",// "../../assets/images/juren13.jpg",// "../../assets/images/juren14.jpg",// "../../assets/images/juren15.jpg",// "../../assets/images/juren16.jpg",],
