详细Laravel5.5执行表迁移命令出现表为空的解决方案

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

rush:plain;"> 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)

In Connection.PHP line 452:

sqlSTATE[42000]: Syntax error or access violation: 1103 Incorrect table name ''

清除配置文件缓存

rush:plain;"> vagrant@homestead:~/Code/laravel-shop$ PHP artisan config:cache

再次执行发布命令，就可以了：

rush:plain;"> 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$
