我正在使用InertiaJS构建Vue3/Laravel应用程序。当我在浏览器中运行应用程序时，它会在控制台中显示以下错误。我是InertiaJS和Vue3的新手，不知道为什么我的组件没有渲染。
Uncaught (in promise) TypeError: l is null
web.php
// Home route.
Route::get('/', [HomeController::class, 'index'])
HomeController.php
public function index()
{
return Inertia::render('Home');
}
我的app.blade.php文件位于下/resources/views/app.blade.php

app.js位于下/resources/js/app.js
// @ts-nocheck
require('./bootstrap');
import { createApp, h } from 'vue'
import { createInertiaApp } from '@inertiajs/inertia-vue3'
import { InertiaProgress } from '@inertiajs/progress'
// Creates the inertia vue app.
createInertiaApp({

setup({ el, App, props, plugin }) {
createApp({ render: () => h(App, props) })
.use(plugin)
.mount(el);
},
});
// Progress bar.
InertiaProgress.init()
终于回家了/resources/js/Pages/Home.vue
<template>
<div>Hello world</div>
</template>
在app.blade.php中向app.js的脚本标记添加defer属性似乎解决了这个问题。

<script src="{{ mix('/js/app.js') }}" defer></script>
