Had the same issue and running
有同样的问题并且正在运行
php composer dump-autoload
php composer dump-autoload
as suggested above by Vape and Oliver fixed the issue.
正如上面 Vape 和 Oliver 所建议的那样解决了这个问题。
php artisan migrate:refresh --seedran like a charm after that :)
php artisan migrate:refresh --seed在那之后像魅力一样跑:)

For some, due to your file structure or composer set-up, all you need to run is:
对于某些人来说，由于您的文件结构或 Composer 设置，您只需要运行：
composer dump-autoload
or
或者
composer.phar dump-autoload
Then, retry the seeder script.
然后，重试播种器脚本。
