[Vuejs]-'template or render function not defined' error

I didn’t mount App.vue

Here is what I’ve changed:

in App.vue

<template>
    <div id="app">
        <h1>{{ message }}</h1>
    </div>
</template>

in main.js

new Vue({
    el: '#app',
    render: h => h(User)
}).$mount('#app')

There’s an error in export default {...}, the fixed version:

export default {
    data: () => ({
        message: 'Hello World'
    })
}
