1、创建

选vue2

 

不要快照

vue2于vue3差异

vue2main。js

import Vue from 'vue'
import App from './App.vue'

Vue.config.productionTip = false

new Vue({
  render: h => h(App),
}).$mount('#app')

vue3 main.js

vue2不能有多个跟组件（div）

代码：Movie.vue

<template>
    <div>
        <div>{{title}}</div>

    </div>
</template>

<script>
export default {
    name:"Movie",
    data:function(){
        return{
            title:"金刚狼"
        }
    },
    methods:{
        
    }
}
</script>

 

<template>
  <div id="app">
    <!-- <img alt="Vue logo" src="./assets/logo.png">
    <HelloWorld msg="Welcome to Your Vue.js App"/> -->
    <movie></movie>
  </div>
</template>

<script>
// import HelloWorld from './components/HelloWorld.vue'
import Movie from './components/Moive.vue'
Movie.name
export default {
  name: 'App',
  components: {
    // HelloWorld
    Movie
  }
}
</script>

<style>
#app {
  font-family: Avenir, Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
  margin-top: 60px;
}
</style>
