1. 在页面中注册

<template>
    <view>
        
    </view>
</template>

<script>
import pageHead from "@/components/page-head/page-head.vue";
export default {
    //注册为子组件
    components: { 
        pageHead
    },  

    data() {
        return {
            
        }
    },
    methods: {

    },
    onLoad:function(){
    }
}
</script>

<style>

</style>

2. 在 main.js 中注册为全局组件

import pageHead from './components/page-head.vue'
Vue.component('page-head', pageHead)
