InvalidArgumentException with message 'Unable to locate factory with    name [default] [App\Reply].'

输入此命令后,控制台中会显示错误：

$threads->each(function ($thread) { factory('App\Reply',10)->create(['thread_id' => $thread->id]); });

我已经阅读了其他类似标题的帖子,但这似乎并非如此.

Laravel 5.2: Unable to locate factory with name [default]

$factory->define(App\User::class,function (Faker $faker) {
    static $password;

return [
    'name' => $faker->name,'email' => $faker->unique()->safeEmail,'password' => $password ?: $password = bcrypt('secret'),'remember_token' => str_random(10),];
});

$factory->define(App\Thread::class,function($faker){
    return [
    'user_id' => function () {
        return factory('App\User')->create()->id;
    },'title' => $faker->sentence,'body' => $faker->paragraph
];
});

$factory->define(App\Reply::class,function($faker){
return [
    'thread_id' => function() {
        return factory('App\Thread')->create()->id;
    },'user_id' => function () {
        return factory('App\User')->create()->id;
    },'body' => $faker->paragraph
];
});
