VUE编译报错 Component template should contain exactly one root element. If you are using v-if on multiple elements, use v-else-if to chain them instead

背景:

在使用VUE添加标签的时候编译报错，报错如下：

Component template should contain exactly one root element. If you are using v-if on multiple elements, use v-else-if to chain them instead.

代码如下：

 <template>
 <el-form ref="form" :model="form" label-width="80px">
   <el-form-item label="活动名称" required>
     <el-input v-model="form.name"></el-input>
   </el-form-item>
 </el-form>

     <el-tabs v-model="Page" type="border-card" @tab-click="handleClick">
         <el-tab-pane label="标签1" name="first">
         </el-tab-pane>
         <el-tab-pane label="标签2" name="second">
         </el-tab-pane>
    </el-tabs>
 </template>
 <script>
   export default {
     data() {
       return {
         cargoPage: 'first',
 form: {
           name: '123',

         }
       };
     },
     methods: {
       handleClick(tab, event) {
       }
     }
   };
 </script>

解决：

加一个<template>后加一个<div></div> 标签，问题解决

 <template>
 <div>
 <el-form ······
 <el-tabs ······
 </div>
 <template>
