nuxt.js写项目时增加错误提示页面操作

<template>
<div class="err_wrap">
<h1 class="error" v-if="error.statusCode === 404">页面不存在或没有数据</h1>
<h1 class="error" v-else>应用发生错误异常</h1>
<nuxt-link class="to_home" to="/">返回首页</nuxt-link>
</div>
</template>

<script>
export default {
props: ['error'],
layout: 'detail',
data() {
return {
msg: '未找到相应页面或没有数据'
}
}
}
</script>

<style scoped>

.to_home {
