运行 Laravel Seeder 时数组到字符串转换错误

Question

ErrorException Array to string conversion当我运行播种器时出现错误。

\n

php artisan db:seed --class=StudentSeeder

在我对 进行更改之前它工作得很好StudentFactory.php，我只是更改了所有的伪造者，而且我不知道是哪个伪造者造成了这个麻烦。

将所有出现的 更改$this->faker->paragraphs为$this->faker->paragraphs(3, true)。

paragraphs格式化程序默认输出一个数组。第二个参数true指示应返回字符串而不是数组。
