推荐答案

在laravel 8中，默认路由名称空间已删除.

In laravel 8 the default route namespace was removed.

尝试更改:

ArticlesTableSeeder.php:

 factory(App\Models\Article::class, 30)->create();

收件人:

\App\Models\Article::factory()->count(30)->create(); 

ArticleFactory.php:

protected $model = App\Models\Article::class;

收件人:

protected $model = \App\Models\Article::class;

，您可能需要更改:

 'title' => $faker->text(50),
            'body' => $faker->text(200)

收件人:

 'title' => $this->faker->text(50),
        'body' => $this->faker->text(200)
