laravel Composer install 突然返回“选项快捷方式不能为空。”

Question

我已经从事 Laravel 7 项目有一段时间了。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

Laravel 版本：7.2 php 7.2 操作系统：Ubuntu

我已经进行了数千次安装，突然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 artisan 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。我已按照升级指南进行操作。但是这个错误堆栈没有给我任何提示问题所在。

Answer 1

这是由于 Symfony 框架最近发生变化，laravel-modules 包中出现问题。 两者均已修复，但我们需要等待其中任一者发布它。 https://github.com/symfony/symfony/pull/53711 https://github.com/nWidart/laravel-modules/issues/1728

Answer 2

1. 检查 psr-4 映射您的composer.json 文件。
2. 更正并删除composer.lock文件
3. 然后运行composer install
