今天在使用一個第三方包 laravel-admin 時，出現了這樣的錯誤：SQLSTATE[42000]: Syntax error or access violation: 1103 Incorrect table name '',折騰了好久，終于知道了解決方法，原來是配置文件的緩存沒有清理。
一、問題
vagrant@homestead:~/Code/laravel-shop$ php artisan admin:install
錯誤提示：
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)

二、解決方案
database/migrations/2016_01_04_173148_create_admin_table.php
<?phpuse Illuminate/Database/Migrations/Migration;use Illuminate/Database/Schema/Blueprint;class CreateAdminTable extends Migration{ /** * Run the migrations. * * @return void */ public function up() { $connection = config('admin.database.connection') ?: config('database.default'); // dd(app('config')); Schema::connection($connection)->create(config('admin.database.users_table'), function (Blueprint $table) { $table->increments('id'); $table->string('username', 190)->unique(); $table->string('password', 60); $table->string('name'); $table->string('avatar')->nullable(); $table->string('remember_token', 100)->nullable(); $table->timestamps(); }); Schema::connection($connection)->create(config('admin.database.roles_table'), function (Blueprint $table) { $table->increments('id'); $table->string('name', 50)->unique(); $table->string('slug', 50); $table->timestamps(); }); Schema::connection($connection)->create(config('admin.database.permissions_table'), function (Blueprint $table) { $table->increments('id'); $table->string('name', 50)->unique(); $table->string('slug', 50); $table->string('http_method')->nullable(); $table->text('http_path')->nullable(); $table->timestamps(); }); Schema::connection($connection)->create(config('admin.database.menu_table'), function (Blueprint $table) { $table->increments('id'); $table->integer('parent_id')->default(0); $table->integer('order')->default(0); $table->string('title', 50); $table->string('icon', 50); $table->string('uri', 50)->nullable(); $table->timestamps(); }); Schema::connection($connection)->create(config('admin.database.role_users_table'), function (Blueprint $table) { $table->integer('role_id'); $table->integer('user_id'); $table->index(['role_id', 'user_id']); $table->timestamps(); }); Schema::connection($connection)->create(config('admin.database.role_permissions_table'), function (Blueprint $table) { $table->integer('role_id'); $table->integer('permission_id'); $table->index(['role_id', 'permission_id']); $table->timestamps(); }); Schema::connection($connection)->create(config('admin.database.user_permissions_table'), function (Blueprint $table) { $table->integer('user_id'); $table->integer('permission_id'); $table->index(['user_id', 'permission_id']); $table->timestamps(); }); Schema::connection($connection)->create(config('admin.database.role_menu_table'), function (Blueprint $table) { $table->integer('role_id'); $table->integer('menu_id'); $table->index(['role_id', 'menu_id']); $table->timestamps(); }); Schema::connection($connection)->create(config('admin.database.operation_log_table'), function (Blueprint $table) { $table->increments('id'); $table->integer('user_id'); $table->string('path'); $table->string('method', 10); $table->string('ip', 15); $table->text('input'); $table->index('user_id'); $table->timestamps(); }); } /** * Reverse the migrations. * * @return void */ public function down() { $connection = config('admin.database.connection') ?: config('database.default'); Schema::connection($connection)->dropIfExists(config('admin.database.users_table')); Schema::connection($connection)->dropIfExists(config('admin.database.roles_table')); Schema::connection($connection)->dropIfExists(config('admin.database.permissions_table')); Schema::connection($connection)->dropIfExists(config('admin.database.menu_table')); Schema::connection($connection)->dropIfExists(config('admin.database.user_permissions_table')); Schema::connection($connection)->dropIfExists(config('admin.database.role_users_table')); Schema::connection($connection)->dropIfExists(config('admin.database.role_permissions_table')); Schema::connection($connection)->dropIfExists(config('admin.database.role_menu_table')); Schema::connection($connection)->dropIfExists(config('admin.database.operation_log_table')); }}清除配置文件緩存
vagrant@homestead:~/Code/laravel-shop$ php artisan config:cache
再次執行發布命令，就可以了：
vagrant@homestead:~/Code/laravel-shop$ php artisan admin:installMigrating: 2016_01_04_173148_create_admin_tableMigrated: 2016_01_04_173148_create_admin_tableAdmin directory was created: /app/AdminHomeController file was created: /app/Admin/Controllers/HomeController.phpExampleController file was created: /app/Admin/Controllers/ExampleController.phpBootstrap file was created: /app/Admin/bootstrap.phpRoutes file was created: /app/Admin/routes.phpvagrant@homestead:~/Code/laravel-shop$
