在nuxt.js项目中如何增加错误提示页面

<template>
<div class="err_wrap">
<h2 class="error" v-if="error.statusCode === 404">页面不存在或没有数据</h2>
<h2 class="error" v-else>应用发生错误异常</h2>
<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>
.err_wrap {
padding: 0.2rem 0.4rem;
text-align: center;
}
.error {
font-size: 0.32rem;
text-align: center;
padding-top: 55%;
color: #582c1a;
padding-bottom: 0.4rem;
}
.to_home {
font-size: 0.3rem;
color: #582c1a;
display: inline-block;
padding-bottom: 3.9rem;
}
</style>
