最初，vue 组件正常运行并加载，但突然我开始收到此错误 [Vue 警告]：未知自定义元素：- 您是否正确注册了组件？对于递归组件，请确保提供“名称”选项。我没有更改任何代码，但在新文件上也收到此错误。

<template>
<v-app>
    <div class="example-component">
        <div class="row justify-content-center">
            <div class="col-md-8">
                <div class="card">
                    <div class="card-header">Example Component</div>

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

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

@section('content')
<div id="app">
<ExampleComponent />

这是我的 vue 文件、我想在其中使用 vue 组件的 home.blade.php 文件以及我的 app.js 文件
