javascript - Vue.js 无法挂载组件 : template or render function not defined

Question

我正在学习如何在 Laravel 中使用 Vue.js series旁白没有收到任何错误，但我在单击更改路线时遇到了以下错误。

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

下面的代码来 self 的app.js:

require('./bootstrap');

window.Vue = require('vue');

import VueRouter from 'vue-router'
Vue.use(VueRouter)

let routes = [{
    path: '/dashboard',
    component: require('./components/Dashboard.vue')
  },
  {
    path: '/profile',
    component: require('./components/Profile.vue')
  }
]

const router = new VueRouter({
  routes
})

Vue.component('example-component', require('./components/ExampleComponent.vue'));

const app = new Vue({
  el: '#app',
  router
});

来 self 的Dashboard.vue的代码片段:

<template>
    <div class="container">
        <div class="row justify-content-center">
            <div class="col-md-8">
                <div class="card">
                    <div class="card-header">Dashboard Component</div>

                    <div class="card-body">
                        I'm an example component.
                    </div>
                </div>
            </div>
        </div>
    </div>
</template>

<script>
  export default {
    mounted() {
      console.log('Component mounted.')
    }
  }
</script>

来 self 的 master.blade.php 布局的代码片段:

//sidebar
<ul>
  <li>
    <router-link to="/dashboard" class="nav-link">Dashboard</li>
  <li>
    <router-link to="/profile" class="nav-link">Profile</li>
</ul>
//content
<div class="container-fluid">
  <router-view></router-view>
</div>

我正在使用 browserSync 和 npm run watch 在 localhost:3000 运行应用程序。这和错误有什么关系吗？

尝试将 .default 添加到您的组件要求:

let routes = [{
    path: '/dashboard',
    component: require('./components/Dashboard.vue').default
  },
  {
    path: '/profile',
    component: require('./components/Profile.vue').default
  }
]
