问题描述
我可以在本地服务器上看到我的数据表，因此我将文件推送到 git，将它们拉到我的本地服务器，并使用 PHP artisan vendor:publish --tag=datatables 发布资产。
我也清除了缓存，并尝试了以下操作：
$ PHP artisan clear-compiled
$ composer dump-autoload
$ PHP artisan optimize:clear
当我尝试查看远程服务器上的数据表时，仍然收到错误 500。这是我的 laravel.log，我希望它可以告诉其他人我不理解的内容。

我需要做什么才能让它在我的远程服务器上工作？请给我哑口无言。我已经在其他网站上这样做了，所以这次我不明白什么不起作用。
解决方法
错误表明未找到类 SewalongsDataTable。因此，您不妨检查一下您的 app.php 或 AppServiceProvider，或者如果您已经将它放入您的 Controllers 中，您可能想要检查一下。
另外，考虑尝试检查 SewalongsDataTable 的命名空间。就我而言，它通常介于这三个之间。
在您发现错误后，仍然无法正常工作，请不要忘记尝试使用 composer dump-autoload
