环境：vue3 + vant-ui4

<div v-for="(info, index) in item.infoListVOs" :key="index">
   <van-popover
  	 v-model:show="showPopover"
     :actions="actions"
     overlay
     placement="bottom-end"
     @select="onSelect(info, index)"
   >
     <template #reference>
       <div class="selectHg">
         {{ actions[0].text }}
         <van-icon name="arrow-down" class="text-#2e99a4 ml-1"></van-icon>
       </div>
     </template>
   </van-popover>
</div>

结果：

点击一个气泡弹出框后，所有的气泡弹出框全部弹出了，因为绑定的是同一个变量showPopover

解决办法：删除v-model,不需要绑定

<div v-for="(info, index) in item.infoListVOs" :key="index">
   <van-popover
     :actions="actions"
     overlay
     placement="bottom-end"
     @select="onSelect(info, index)"
   >
     <template #reference>
       <div class="selectHg">
         {{ actions[0].text }}
         <van-icon name="arrow-down" class="text-#2e99a4 ml-1"></van-icon>
       </div>
     </template>
   </van-popover>
</div>

结果
