Considering that Service is a model you created, and that this model is inside the app folder, within the App namespace, try this:
考虑到 Service 是您创建的模型，并且该模型位于 app 文件夹内的 App 命名空间内，请尝试以下操作：
Fix your ServiceTableSeeder.php header:
修复您的 ServiceTableSeeder.php 标头：
<?php
use Illuminate\Database\Seeder;
use App\Service;
class ServiceTableSeeder extends Seeder {
public function run()
{
Service::create(
array(
'title' => 'Web development',
'description' => 'PHP, MySQL, Javascript and more.'
)
);
Service::create(
array(
'title' => 'SEO',
'description' => 'Get on first page of search engines with our help.'
)
);
}
}
As you have moved your models to app\models, you must declare that in each model file:
当您将模型移动到 app\models 时，您必须在每个模型文件中声明：
Models.php:
模型.php：
namespace App\Models;
And in your seed file, use:
在你的种子文件中，使用：
use App\Models\Service.php;
Are you using composer to autoload your files? If so, update your composer.json file to include your models location:
您是否使用 Composer 自动加载文件？如果是这样，请更新您的 composer.json 文件以包含您的模型位置：
"autoload": {
"classmap": [
"database",
"app/Models"
],
"psr-4": {
"App\": "app/"
}
},
And finally, run this in your command line:
最后，在命令行中运行它：
composer dump-autoload

For those who are facing the same issue, confirm your APP_ENV variable from .env file cause Laravel don't let us to run db:seed if we set
对于那些面临同样问题的人，请从 .env 文件中确认您的 APP_ENV 变量，因为如果我们设置，Laravel 不会让我们运行 db:seed
'APP_ENV = Production'
'APP_ENV = 生产'
for the sake of database records.
为了数据库记录。
So, make sure you set value of APP_ENV to 'staging' or 'local' and then run php artisan db:seed
因此，请确保将 APP_ENV 的值设置为“staging”或“local”，然后运行 php artisan db:seed

I think the problem is your ServiceTableSeeder.phpfile. You should make sure the class filename in this file is ServiceTableSeederand not DatabaseSeeder
我认为问题在于您的ServiceTableSeeder.php文件。你应该确保这个文件中的类文件名是ServiceTableSeeder而不是DatabaseSeeder
