Laravel5.5执行表迁移命令 详细Laravel5.5执行表迁移命令出现表为空的解决方案
Corwien 人气:2今天在使用一个第三方包 laravel-admin 时，出现了这样的错误：SQLSTATE[42000]: Syntax error or access violation: 1103 Incorrect table name '',折腾了好久，终于知道了解决方法，原来是配置文件的缓存没有清理。
一、问题
vagrant@homestead:~/Code/laravel-shop$ php artisan admin:install
错误提示：
In Connection.php line 664:
SQLSTATE[42000]: Syntax error or access violation: 1103 Incorrect table name '' (SQL: create table `` (`id` int uns
igned not null auto_increment primary key, `username` varchar(190) not null, `password` varchar(60) not null, `name
` varchar(255) not null, `avatar` varchar(255) null, `remember_token` varchar(100) null, `created_at` timestamp nul
l, `updated_at` timestamp null) default character set utf8mb4 collate utf8mb4_unicode_ci)

清除配置文件缓存
vagrant@homestead:~/Code/laravel-shop$ php artisan config:cache
再次执行发布命令，就可以了：
vagrant@homestead:~/Code/laravel-shop$ php artisan admin:install Migrating: 2016_01_04_173148_create_admin_table Migrated: 2016_01_04_173148_create_admin_table Admin directory was created: /app/Admin HomeController file was created: /app/Admin/Controllers/HomeController.php ExampleController file was created: /app/Admin/Controllers/ExampleController.php Bootstrap file was created: /app/Admin/bootstrap.php Routes file was created: /app/Admin/routes.php vagrant@homestead:~/Code/laravel-shop$
