Php Laravel；Composer安装突然返回选项快捷方式不能为空.

我一直在做一个Laravel 7项目已经有一段时间了.突然，我的composer install返回以下错误

Generating optimized autoload files
Class Modules\Tests\ThumbnailTest located in ./Modules/Media/Tests/ThumbnailTest.php does not comply with psr-4 autoloading standard. Skipping.
> Illuminate\Foundation\ComposerScripts::postAutoloadDump
> @php artisan package:discover --ansi
                                       
  An option shortcut cannot be empty.                                     

Script @php artisan package:discover --ansi handling the post-autoload-dump event returned with error code 1

==同步，由长者更正== PHP 7.2 PHP 7.2 操作系统:Ubuntu-Ubuntu

我已经安装了数千次，现在这个错误阻碍了我的项目.

下面是错误的堆栈跟踪

我的所有Arartian命令都返回相同的错误:"选项快捷方式不能为空"

最近，我升级到了Laravel 7.我遵循了升级指南.但是这个错误堆栈并没有给我任何提示，问题出在哪里.
