Getting In Container.php line 752: Class RoleTableSeeder does not exist error, when trying to seed a role in Laravel
提问by Bobimaru
Currently, I am trying to create roles for my application, unfortunately I am having some troubles. Whenever I run php artisan migrate --seed, I get the error I've written in the title. Honestly, I feel like I've messed up something really simple like a name but I just can't find my mistake. I'd appreciate any help.
目前，我正在尝试为我的应用程序创建角色，不幸的是我遇到了一些麻烦。每当我运行 php artisan migrate --seed 时，我都会收到标题中写的错误。老实说，我觉得我把名字这样简单的东西搞砸了，但我就是找不到我的错误。我很感激任何帮助。

As mentioned in the comments:
正如评论中提到的：
Run: composer dump-autoload.
运行：composer dump-autoload。
If Composer\Exception\NoSslExceptionexception is thrown, you may need to run composer config -g -- disable-tls truebefore composer dump-autoload.
如果Composer\Exception\NoSslException抛出异常，您可能需要composer config -g -- disable-tls true在composer dump-autoload.

I had the same issue as above the composer command didn't do the trick.
我遇到了与上面相同的问题，composer 命令没有解决问题。
on Laravel 5.5 I ran
在 Laravel 5.5 上我跑了
php artisan cache:clear
and then all my new created seeder classes were found
然后找到了我所有新创建的播种机类

I have faced the same issue on PH 7.2.* with Lavarel 5.5.*
我在 PH 7.2.* 和 Lavarel 5.5.* 上遇到了同样的问题
Solution very easy - use the namespace:
解决方案非常简单 - 使用命名空间：
php artisan db:seed --class=Modules\{moduleName}\Database\Seeders\{className}DatabaseSeeder
Also here:
也在这里：
$this->call('Modules\{moduleName}\Database\Seeders\{className}TableSeeder');
