My \ NameSpace \ Database \ Seeders \ RoleTableSeeder

如何解决My \ NameSpace \ Database \ Seeders \ RoleTableSeeder

我的包装中收到不赞成使用的警告，说某些文件不符合psr-4自动加载标准。

我有一个laravel 8项目，在其中加载我的包。当我在laravel目录中运行composer update时，会看到以下消息：

弃用声明：位于./vendor/my/name-space/src/database/seeders/RoleTableSeeder.php中的类My \ NameSpace \ Database \ Seeders \ RoleTableSeeder不符合psr-4自动加载标准。在Composer v2.0中将不再自动加载。在phar：///usr/local/bin/composer/src/Composer/Autoload/ClassMapGenerator.php：201

my/name-space/src/Database/Seeders/RoleTableSeeder.php

<?php

namespace My\NameSpace\Database\Seeders;

use Illuminate\Database\Seeder;
use Spatie\Permission\Models\Role;

class RoleTableSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        if ( ! Role::query()->where('name','=','Administrator')->exists()) {
            \Artisan::call('permission:create-role Administrator web');
        }

        if ( ! Role::query()->where('name','User')->exists()) {
            \Artisan::call('permission:create-role User web');
        }
    }
}

我已经读过autoloading standard，但我并没有真正发现问题所在。我还有许多其他文件未给出此错误，它们具有相同的目录结构和文件命名。
