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>
