Vue.js-無法安裝組件：模板或渲染函數未定義

Question

我不確定自己在做什么錯。 我收到以下錯誤：

控制台中的錯誤消息：

[Vue warn]: Failed to mount component: template or render function not defined.

found in

---> <VueChartjs>
       <Chatjsvue> at src\components\vueChartjs\Chatjsvue.vue
         <App> at src\App.vue
           <Root>

index.js

import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from '@/components/HelloWorld'


Vue.use(Router)

export default new Router({
  routes: [
    {
      path: '/',
      name: 'HelloWorld',
      // component: HelloWorld
      component: require('../components/HelloWorld.vue').default
    }
  ]
})

應用程序

<template>
  <div id="app" class="container">
    <img src="./assets/logo.png" class="logo">

    <!-- chartjs -->
    <div class="chartjsvue">
      <Chatjsvue></Chatjsvue>
    </div>
    <div class="clear"></div>
    <!-- chartjs -->

  </div>
</template>

<script>
import Chatjsvue from '@/components/vueChartjs/Chatjsvue'

export default {
  name: 'App',
  components: {
    Chatjsvue
  }
}
</script>

Chatjsvue.vue

<template src="../../views/chartjshtml/chartsjs.html"></template>

<script>
  import Chartjsvue from '@/assets/javascripts/chartjs'

  export default {
    components: {
      'vue-chartjs': Chartjsvue 
    }
  };
</script>

Chartsjs.html

<div class="wrapper">
  <vue-chartjs></vue-chartjs>
</div>

chartjs.js

file is rmpty- no code in the file

錯誤指的是什么，需要采取什么措施來解決？

Answer 1

我認為問題是您的chartjs.js為空。 您需要做：

import template from './chartjs.html' // in your questions it's chartsjs.html, please help to correct it
export default {
  template: template
}

Answer 2

您的chartjs.js文件不應為空。 它應該是帶有可渲染模板的Vue組件。 任何JavaScript都可以在script標簽本身中編寫。

組件對象應僅包含您需要在當前組件中使用的Vue組件的列表。 並且每個組件都必須有一個模板。

感謝所有為回答做出貢獻的人。 js文件不應為空。 這是顯示chartjs所有圖表的完整代碼
