2、原因在于包 tamayo/laravel-scout-elastic 需要安装 elasticsearch/elasticsearch。但是，在执行命令 composer require nuwave/lighthouse 之前，也执行了命令：php artisan package:discover –ansi，未报错的。如图2
图2
3、深入分析，在执行命令 composer require nuwave/lighthouse 时，安装了包 tamayo/laravel-scout-elastic，即包 tamayo/laravel-scout-elastic 被写入了 composer.lock 文件，而在执行命令 composer require nuwave/lighthouse 之前，composer.lock 文件中不存在包 tamayo/laravel-scout-elastic。如图3
图3
4、由此得出结论，composer.lock 与 composer.json 文件并未严格保持一致。在执行命令 composer require nuwave/lighthouse 时，才让 composer.lock 与 composer.json 文件保持了一致性。
5、执行命令：composer require elasticsearch/elasticsearch 后，在执行 php artisan package:discover –ansi 时，不再报错。
