找不到类'Respect \ Validation \ Validator'

Question

您好我在使用SLIM时遇到的这个错误真的需要帮助。我收到这个错误：

Type: Error
Message: Class 'Respect\Validation\Validator' not found
File: /storage/content/90/223690/marbleuf.se/public_html/cart/app/Validation/Forms/OrderForm.php
Line: 12

以下是来自OrderForm.php的代码：

<?php

namespace Cart\Validation\Forms;

use Respect\Validation\Validator as v;

class OrderForm
{
    public static function rules()
    {
        return [
            'email' => v::email(),
            'name' => v::alpha(' '),
            'address1' => v::alnum(' -'),
            'address2' => v::optional(v::alnum(' -')),
            'city' => v::alnum(' '),
            'postal_code' => v::alnum(' '),
        ];
    }
}

根据我的假设，您的使用声明应为以下内容

use Cart\Validation\Validator as v;

不是

use Respect\Validation\Validator as v;
