Question

我正在尝试在laravel 5.8上使用Migration，但我收到此错误消息

C:\wamp\www\work_p\laravel\lvl1>php artisan migrate
Migrating: 2014_10_12_000000_create_users_table

我在这里找到的所有解决方案都说我必须删除表格；

但是我的表上没有数据，用户表和所有其他表上都有数据。没有删除表，有没有解决此错误的方法？我确实尝试过使用此解决方案

public function boot()
{
    Schema::defaultStringLength(191);
}

问题仍然存在

如果您不想专门运行该迁移，请在数据库上运行此查询

INSERT INTO `migrations` (`id`, `migration`, `batch`) VALUES (NULL, '2014_10_12_000000_create_users_table', '1');

laravel 5.8迁移基本表或视图已经存在，无需删除表
