[Vue warn]: Invalid prop: validation failed. Expected one of ["", "large", "default", "small"], got value "medium".

上代码：

<div class="bottom-btn mb-20">
  <el-button @click="submit" otitle="按钮-确认" size="medium" type="primary">确认</el-button> 
  <el-button @click="router.go(-1)" otitle="按钮-返回" size="medium">返回</el-button>
</div>

解决：

问题出在element-plus 的el-button组件没有medium这个属性了 删除或者改成large就行了
