PHP artisan db:seed --class=ProductsSeeder 提示 Undefined variable: factory？

看看你的 ProductsSeeder 里对应的 factory 文件

@Ken

@KangJian ProductSkuFactory

<?php

use Faker\Generator as Faker;

$factory->define(App\Models\ProductSku::class, function (Faker $faker) {
    return [
        'title'       => $faker->word,
        'description' => $faker->sentence,
        'price'       => $faker->randomNumber(4),
        'stock'       => $faker->randomNumber(5),
    ];
});

@Ken ProductSkuFactory 就是这段代码有问题，自己仔细对比吧
