我有一个遗留的Laravel项目，我正在尝试向其中添加“ guzzlehttp / guzzle”：“〜5.0”，因此我正在运行命令：composer需要将“ guzzlehttp / guzzle：〜5.0”添加到输出如下所示。当我尝试将邮件驱动程序更改为mailgun时，输出为：
FatalErrorException in MailgunTransport.php line 79:
Class 'GuzzleHttp\Post\PostFile' not found
Laravel框架已锁定在composer.lock中：5.0.33
这就是所有composer.lock：https://pastebin.com/dBJjDBtJ
这是composer.json的全部内容：https://pastebin.com/UQNhKkyA
这是尝试运行composer require "guzzlehttp/guzzle:~5.0"
