当我尝试执行php artisan migrate:fresh --seed命令时出现错误。我不明白它们的全部含义，也不知道是什么原因造成的。问题描述如下。
工厂文件 PostFactory.php：
<?php
namespace Database\Factories;
use App\Models\Post;
use Illuminate\Database\Eloquent\Factories\Factory;
class PostFactory extends Factory
{
/**
* The name of the factory's corresponding model.
*
* @var string
*/
protected $model = Post::class;
/**
* Define the model's default state.
*
* @return array
*/
public function definition()
{
$title = $faker->realText(rand(10, 40));
$short_title = \Illuminate\Support\Str::length($title) > 30 ? mb_substr($title, 0, 30) . "..." : $title;
$created = $faker->dateTimeBetween("-30days", "-1days");
return [
"title" => $title,
"short_title" => $short_title,
"author_id" => rand(1, 4),
"descr" => $faker->realText(100, 500),
"created_at" => $created,
"updated_at" => $created
];
}
}
DatabaseSeeder.php：
<?php
namespace Database\Seeders;
use Illuminate\Database\Seeder;
class DatabaseSeeder extends Seeder
{
/**
* Seed the application's database.
*
* @return void
*/
public function run()
{
\App\Models\User::factory()->count(4)->create();
\App\Models\Post::factory()->count(15)->create();
}
}
当我执行 php artisan migrate:fresh --seed 我得到这些错误：
Illuminate\Database\QueryException

我已经检查了错误描述中提供的文件中的行，但我不知道是什么导致了错误。
任何帮助都会非常感激

我尝试按照@Rwd 的建议将配置文件中的“localhost”更改为“127.0.0.1”。以前的错误消失了。但现在我遇到了其他错误：
ErrorException

替换$faker为$this->faker@Cristea 建议的，现在得到以前的错误：
1 C:\xampp\htdocs\laralove\vendor\laravel\framework\src\Illuminate\Database\Connectors\Connector.php:70
PDOException::("SQLSTATE[HY000] [2002] , .. .

2 C:\xampp\htdocs\laralove\vendor\laravel\framework\src\Illuminate\Database\Connectors\Connector.php:70
PDO::__construct("mysql:host=localhost;port=3306;dbname=laralove", "root", "", [])
正如@Rwd 建议的那样，localhost 仍然在 .env 和 database.php 中更改为 127.0.0.1
