laravel - 如何在 Laravel 中实例化 vue 3 应用程序而不使用父 App.vue？

Question

我正在 Laravel 8.x 应用程序中工作，并且安装 vue 2.6.12 的时间最长。我正在努力升级以将 Vue 3 与 laravel 一起使用，并与 Webpack 一起使用。我已经更新了我的package.json脚本并安装以下内容以实现 Vue 3 兼容性:

{
    "scripts": {
        "dev": "npm run development",
        "development": "mix",
        "watch": "mix watch",
        "watch-poll": "mix watch -- --watch-options-poll=1000",
        "hot": "mix watch --hot",
        "prod": "npm run production",
        "production": "mix --production"
    },
    "devDependencies": {
        "bootstrap": "^4.5.2",
        "jquery": "^3.4",
        "laravel-mix": "^6.0.39",
        "laravel-mix-polyfill": "^2.0.0",
        "vue-loader": "^16.8.3"
    },
    "dependencies": {
        "@vue/compiler-sfc": "^3.2.24",
        "jquery-validation": "^1.17.0",
        "jquery.nicescroll": "^3.7.6",
        "jquery.scrollto": "^2.1.2",
        "mdb-vue-ui-kit": "^1.7.0",
        "sass": "^1.21.0",
        "sass-loader": "^7.1.0",
        "vue": "^3.2.24",
        "vue-moment": "^4.1.0",
        "vue-router": "^4.0.12",
        "vue-template-compiler": "^2.6.14",
    }
}

我从来没有主App.vue文件，因为它最初是一个 Laravel 应用程序，后来引入了 Vue。相反，我在我的 /resources/js/app.js 中创建了(现在使用 vue 2 和 vue3)初始 vue 对象。文件。这刚刚结束了<div id="app">位于我的父 Blade.php 文件中。但现在使用 Vue 3，我不确定如何在不手动添加 App.vue 文件的情况下执行此操作。是否需要这样做，或者我还可以做些什么来在我的 Laravel 应用程序中配置 vue 3 实例化？

Vue 2 设置(工作)

const router = new VueRouter({
  mode: 'history',
  routes: routes
});

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

Vue 3 实例化尝试

import Vue, {createApp } from 'vue';
import router from './router/routes.js';
const app = new Vue({});

createApp(app)
    .use(router)
    .use(require('vue-moment'))
    .use(VueToast)
    .mount('#app')

运行时遇到的主要错误 npm run dev

您可以将全局组件注册到您正在创建的应用程序。

import {createApp, defineComponent } from 'vue';
import router from './router/routes.js';
import MyComponent from '@/components/MyComponent.vue'

// Root vue component
const root = defineComponent({/* ... */})

//Create the app
const app = createApp(root)

//Configure the app
app.use(router)
   .use(require('vue-moment'))
   .use(VueToast)

//Attach global components to the app
app.component('my-component', MyComponent)

//Mount the app
app.mount('#app')
