vue.esm.js?efeb:628 [Vue warn]: Unknown custom element: <dv> - did you register the component correctly? For recursive components, make sure to provide the "name" option.

found in

---> <Home> at src/components/home.vue
<App> at src/App.vue
<Root>

报该错误请大佬们解答，

路由如下

import Vue from 'vue'
import Router from 'vue-router'
import home from "../components/home";
import login from "../components/login";
import more from "../components/more";
import 'element-ui/lib/theme-chalk/index.css';
import ElementUI from 'element-ui';

// import {
//   Button,Icon,Link,Radio,Row,Col,Container,Header,Main,Footer,Aside,
//   Carousel,CarouselItem,
// } from 'element-ui';
Vue.use(ElementUI)
Vue.use(Router)

export default new Router({
  routes: [
    {
      path:'/',
      redirect:"/home"
    },
    {
      path: '/home',
      component:home
    },
    {
      path: '/login',
      component:login
    },
    {
      path: '/more',
      component:more
    },
  ]
})

main 如下

import Vue from 'vue'
import App from './App'
import router from './router'
import store from './store'
import vuex from 'vuex'
Vue.use(vuex)
Vue.config.productionTip = false
new Vue({
  el: '#app',
  router,
  store,
  components: { App },
  template: '<App/>'
})

其中一个views视图的vue如下

<script>

import {searchMusic,musicPlay,hotMusic,hotComment} from "../Api/api.js";
export default {
  name: "home",
  created() {
    hotMusic().then((res)=>{
      console.log(res);
      this.musicList=res.data.data.dailySongs;
      console.log(this.musicList)
    })
  },
  data() {
    return {
      //用户输入
      user_input:'',
      //歌曲列表
      musicList: [],
      //歌曲地址
      musicSrc:'',
      //歌曲列表显示或隐藏
      active:true,
      //歌曲列表标题切换
      titleActive:false,
      //歌曲头像
      mAvatar:'',
      //头像显示指针
      isAvatar:false,
      //评论列表
      commentList:[],
      //歌曲评论指针
      com_body:false,
    }
  },
  methods:{
    //歌曲搜索
    searchMusic(){
      var that = this;
      searchMusic({keywords:this.user_input}).then((res)=>{
        console.log(res)
        that.musicList =res.data.result.songs;
        console.log(that.musicList)
        that.active = true;
        this.titleActive=true;
      })
    },
    //关闭搜索列表
    cls(){
      this.active = false;
    },
    //打开搜索列表
    opn(){
      this.active = !this.active;
    },
    // 歌曲播放
    playMusic(id,index){
      var that= this;
      //调出歌曲头像和评论
      this.com_body=true;
      this.isAvatar= true;
      musicPlay({id:id}).then((res)=>{
        // console.log(res)
        // console.log(id)
        that.musicSrc = res.data.data[0].url;
        // console.log(that.musicSrc)
        that.mAvatar = that.musicList[index].al.picUrl
        hotComment({id:id}).then((res)=>{
          console.log(res)
        })
        hotComment({id:id,limit:50}).then((res)=>{
          console.log("--------")
          console.log(res)
          that.commentList = res.data.comments;
        })
      })

    }
  }
}
