Php 类别'；GUZLE http\Post\PostFile'；找不到

我有一个遗留的Laravel项目，我正试图将“guzzlehttp/guzzle”：“~5.0”添加到该项目中，因此我正在运行命令：composer require“guzzlehttp/guzzle:~5.0”，其输出如下所示。当我尝试将邮件驱动程序更改为

mailgun

时，这是输出：

FatalErrorException in MailgunTransport.php line 79:
Class 'GuzzleHttp\Post\PostFile' not found

Laravel框架作为锁定在composer中。锁定：5.0.33

这是composer.lock的全部内容：

以下是composer.json的全部内容：

这是尝试运行

composer require“guzzlehttp/guzzle:~5.0”的输出

我已经尝试运行composer更新、自动加载和删除缓存

---

注意：如果这是一个格式不好的文件，或者它缺少了一些东西，我真的很抱歉，我正在努力学习。谢谢

在运行

require

之前，是否尝试删除

composer.lock

和

vendor

？在运行

require

之前，是否尝试删除

composer.lock

和

vendor

？
