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.
<template> <!-- 面包屑 --> <el-breadcrumb separator="/"> <el-breadcrumb-item :to="{ path: '/home' }">首页</el-breadcrumb-item> <el-breadcrumb-item>权限管理</el-breadcrumb-item> <el-breadcrumb-item>权限列表</el-breadcrumb-item> </el-breadcrumb> <!-- //卡片 --> <el-card>123</el-card> </template>
解决办法，用div包起来
<template> <div> <!-- 面包屑 --> <el-breadcrumb separator="/"> <el-breadcrumb-item :to="{ path: '/home' }">首页</el-breadcrumb-item> <el-breadcrumb-item>权限管理</el-breadcrumb-item> <el-breadcrumb-item>权限列表</el-breadcrumb-item> </el-breadcrumb> <!-- //卡片 --> <el-card>123</el-card> </div>
