Question

我正在遵循教程DevMarketer的形式，当Vue commands迷路了

不要使用我的代码。我运行npm run dev和npm run watch来生成错误，但是什么也没发生，似乎我的代码完全可以正常工作，然后我在浏览器上检查了developer tool，然后从{{1 }}。

错误消息是：
[警告]：属性或方法“ password_options”未在实例上定义，但在渲染期间被引用。通过初始化属性，确保在data选项中或对于基于类的组件，此属性都是反应性的。参见：https://vuejs.org/v2/guide/reactivity.html#Declaring-Reactive-Properties。

这是细分：

- <div v-model="password_options">: v-model is not supported on this element type. If you are working with contenteditable, it's recommended to wrap a library dedicated for that purpose inside a custom component.

您正在将模型绑定到div（仅适用于输入），如果只想显示或隐藏div，请将v-model更改为v-if

<div class="management-area" id="app" style="position: absolute;top: 4rem;left: 200px;right: 0;">
    <div class="flex-container">
<div class="columns m-t-10">
    <div class="column">
        <h1 class="title">Edit User</h1>
    </div>
</div>
<div class="columns">
    <div class="column">
        <h1 class="m-t-0"></h1>
        <form action="{{route('users.update', $user->id)}}" method="POST">
        {{method_field('PUT')}}
        {{csrf_field()}}
            <div class="field">
                <label for="name" class="label">Name</label>
                <p class="control">
                    <input type="text" class="input" name="name" id="name" value="{{$user->name}}">
