Class 在验证库中找不到验证器

Question

我是 composer 的新手，但我可以从 cmd 中获取 vendor、composer.lock 和 composer.json，然后我将它们粘贴到我的项目中而没有 Validation_Master 文件夹。我的项目路径：C:\wamp64\www\php Projects\project 1\(here there are test.php and vendor, composer.lock and composer.json) Validation_Master 文件夹路径：C:\wamp64\www\php Projects\Validation_Master 我的代码是：

<?php
    require "vendor/autoload.php";
    use Respect\Validation\Validator as v;
    $number = 123;
    v::numeric()->validate($number);
?>

但是上面的代码给我以下错误：

Fatal error: Class 'Respect\Validation\Validator' not found in C:\wamp64\www\php Projects\project 1\test.php

我做了什么？！！？
将 Validation_Master 文件夹复制到 test.php ==>（失败）
的路径将 Vendor 文件夹复制到 Validation_Master 文件夹的路径并从那里需要 ==>（失败）
大量操作命名空间并将命名空间Respect\Validation添加到代码==>（失败）
有什么问题？？？？我如何使用 Respect Validation Library ??????请基本上回答我（我之前看过文档但没有帮助）

composer.json代码：

        "test": "./vendor/bin/phpunit"
    }

autoload.php 代码：

<?php
require_once  __DIR__ . '/composer' . '/autoload_real.php';

return ComposerAutoloaderInit46e0d859a60be6f2acf30ed92a2228ad::getLoader();

我很感激也很抱歉我写了很多

更新：我的问题是这样的post：Why my autoload.php of composer doesn't work?，但它没有帮助
我也在cmd中运行 composer dump-autoload ==>（失败）

Answer 1

在我看来，您似乎复制了 respect/validation 库的 composer.json，并试图将其用作您项目的 composer.json。这是一个完全错误的做法。

将此用作您的项目composer.json:

{
  "require": {
    "respect/validation": "^1.0"
  }
}

然后：

运行 composer install,
运行又是你的脚本。
