Illuminate\Contracts\Container\BindingResolutionException :目标类[Database\Seeders\PermissionTableSeeder]不存在

所以我对种子有问题，当我第一次看到这个错误时，我想可能文件和表的名称不一样。我试着查找它，找到的是这个链接in laravel 8 with seeding , i has this issue Target class [TableSeeder] does not exist，它说要编辑数据库\种子到数据库\种子的名称空间，但这不是问题，因为它已经正确了。它说要检查composer.json的自动，并改变种子为种子.
"autoload": {
"psr-4": {
"App\\": "app/",
"Database\\Factories\\": "database/factories/",
"Database\\Seeders\\": "database/seeders/"
}
},但我也有和他们建议完全一样的东西。在那之后，也有人建议做作曲家自传，这就是结果.

我得到了答案，所以首先，显然表播种机的名字不对。然后我得到了这个错误..。
Error
Class "Database\Seeders\permissions" not found
at \database\seeders\PermissionsTableSeeder.php:28
24▕ 'title' => 'task_access',
25▕ ],
26▕ ];
27▕
➜ 28▕ permissions::insert($permissions);
29▕ }
30▕ }
31▕在我搜索完互联网之后，我找到了这个https://laracasts.com/discuss/channels/laravel/laravel-8-class-databaseseedersdb-not-found。所以我读了答案，所以你需要在你的表播种机中添加use Illuminate\Support\Facades\DB;，这样它就可以调用数据库来让它工作。所以现在我的PermissionsTableSeeder.php看起来是这样的，它运行得很好。
<?php
namespace Database\Seeders;
use Illuminate\Database\Console\Seeds\WithoutModelEvents;
use Illuminate\Database\Seeder;
use Illuminate\Support\Facades\DB;
class PermissionsTableSeeder extends Seeder
{
/**
* Run the database seeds.
*
* @return void
*/
public function run()
{
$permissions = [
[
'id' => 1,
'title' => 'user_access',
],
[
'id' => 2,
'title' => 'task_access',
],
];
DB::table('permissions')->insert($permissions);
}
