我有一个组件：
<player-info :data="player"></player-info>
我想将vue-mask-input plugin用作子组件：
<masked-input v-model="date" mask="11 / 11 / 1111" placeholder="Date">
这是整个组成部分：
<template>
<div id="info" class="player-info-card-content section-card">
<div class="row">
<div class="col-12">
<h5 class="section-title"><i class="ion-ios-list-outline title-icon"></i> Overview</h5>

import MaskedInput from 'vue-masked-input';
export default {
props: ['data'],
data () {
return {
player: this.data.data,
edit: false,
date: '',

},
computed: {
link() {
return `/player/info/edit/${this.player.id}`;
}
},
components: {
MaskedInput
}
}
</script>
在更新到Vue v.2.4.4之前，我一直警告它是一个片段实例：
[Vue警告]：属性“v-model”，“mask”，“placeholder”被忽略 component，因为该组件是一个片段实例：
将Vue更新为v.2.4.4后，警告消失了，但我收到了一个新错误：
[Vue warn]: Failed to mount component: template or render function not
defined.

这是我页面上的父组件：
<div><player :player="{{ $player }}" :videos="{{ $videos }}"></player></div>
此父组件由以下子组件组成：
<template>
<div class="row">
<div class="col-md-3">
<div>
<player-card :data="player"></player-card>
</div>
</div>
<div class="col-md-9">
<div>
<player-info :data="player"></player-info>
</div>
<div>
<player-videos :data="videos"></player-videos>
</div>
<div>
<player-stats :player="player.data.seasons"></player-stats>
</div>
</div>
</div>
</template>
我正在导入Vue：
import Vue from 'vue/dist/vue';
window.Vue = Vue;
这就是我创建Vue实例的方式：
const app = new Vue({
el: 'body',
data: window.videoApp
});
我做错了什么，我该如何解决？

您不能选择body标签作为为vue实例创建div所需的主要元素。你需要像这样创建vue实例;
const app = new Vue({
el: '#app',
data: {
// Some data...
},
methods: {
// Your methods...
}
})
你的html文件看起来应该是这样的;
...
<body>
<div id="app">
<!-- Vue instance selects and creates components in this div -->
</div>
</body>

参考：vue-masked-input，显示以/＆gt;
结束<div><masked-input v-model="date" mask="11 / 11 / 1111" placeholder="Date" /></div>
但你没有自我关闭的斜杠或结束标记......
<div><masked-input v-model="date" mask="11 / 11 / 1111" placeholder="Date"></div>
