我尝试将我的jQuery迁移到Vue框架，我使用Laravel 5.6和webpack来构建我的项目，但是我的Vue组件没有显示出来。
当我运行命令npm run dev时，我成功地构建了项目：

之后，我使用PHP Artisan Serve在我的浏览器中显示Web，它确实这样做了，但没有一个组件显示出来。
当我检查源代码时，组件呈现如下内容：

但由于某种原因我看不到组件
这是我的app.js文件：

/**
 * First we will load all of this project's JavaScript dependencies which
 * includes Vue and other libraries. It is a great starting point when
 * building robust, powerful web applications using Vue and Laravel.
 */
 
/*
require('./bootstrap');
*/

window.Vue = require('vue');

/**
 * Next, we will create a fresh Vue application instance and attach it to
 * the page. Then, you may begin adding components to this application
 * or customize the JavaScript scaffolding to fit your unique needs.
 */

Vue.component('related-post-list', require('./components/RelatedPostList.vue'));
Vue.component('example-component', require('./components/ExampleComponent.vue'));

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

我的Webpack文件：

let mix = require('laravel-mix');

/*

 | Mix Asset Management
 |--------------------------------------------------------------------------
 |
 | Mix provides a clean, fluent API for defining some Webpack build steps
 | for your Laravel application. By default, we are compiling the Sass
 | file for the application as well as bundling up all the JS files.

 */

mix.js('resources/assets/js/app.js', 'public/js')
   .sass('resources/assets/sass/app.scss', 'public/css');
