推荐答案

来自 laravel 8

---

要适应这些更改，请将 Database \ Seeders 名称空间添加到播种器类.

From laravel 8 Seeders and factories are now namespaced

---

To accommodate for these changes, add Database\Seeders namespace to your seeder classes.

namespace Database\Seeders;

此外，将所有种子文件从先前的 database/seeds 目录移动到 database/seeders 文件夹.

In addition, move all seeder files from previous database/seeds directory to database/seeders folder.

在您的情况下，请删除以 use Database \ Seeders \ ...
开头的所有行来自 DatabaseSeeder.php 文件

In your case remove all lines started with use Database\Seeders\...
from DatabaseSeeder.php file

它应该解决问题，

您还可以运行 dump-autoload &有种子的新移民，

You can also run dump-autoload & fresh migration with seed,

composer dump-autoload

php artisan migrate:fresh --seed
