Question

vue的新手，将其安装在Laravel中后，我制作了一个新组件，但未在浏览器中显示，浏览器在开发人员工具中发出警告，在开发人员工具>控制台中显示：

  app.js:37960 [Vue warn]: Failed to mount component: 
  template or render function not defined.
  found in

---> <TaskForm>
<Root>
warn @ app.js:37960
app.js:46384 You are running Vue in development mode.
Make sure to turn on production mode when deploying for production.
See more tips at https://vuejs.org/guide/deployment.html

代码中是否存在任何问题，或者是否有解决此问题的解决方案？

组件：

   <template>

    <div class="col-md-8">
      <div class="card card-default">
         <div class="card-header">Task Form</div>

         <div class="card-body">
            <form action="./api/task" method="POST">
              <div class="form-group">
                <input type="text" name="title" placeholder="Task title" class="form-control">
              </div>
              <div class="form-group">
               <input type="submit" value="Add Task" class="btn btn-info">
              </div>
            </form>
        </div>
    </div>
 </div>

 </template>

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

app.js：

  require('./bootstrap');

 window.Vue = require('vue');

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

  Vue.component("task-form", require('./components/TaskForm.vue'));

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

这是app.blade.php：app.blade.php：
