did you register the component correctly? For recursive components, make sure to provide the "name"

在引入该组件时，报了个这样的警告，组件死活引入不到，什么原因呢？

<template>

  <div id="app">

    我是APP.vue组件----{{msg}}

    <hr/>

    <Father/>

  </div>

</template>

<script>

import Father from './components/Father.vue'

// import Vue from 'vue'

// Vue.component('Father',Father)

export default {

 name:'app',

 data() {

   return {

     msg: 'hellow-word'

   }

 },

 components:{//局部注册组件..

   Father

 }

}

</script>

经过仔细对比代码，发现我用的component，应该是components,怪自己不仔细了！
