Laravel5.5執行表遷移命令出現表為空怎么辦

這篇文章主要介紹Laravel5.5執行表遷移命令出現表為空怎么辦，文中介紹的非常詳細，具有一定的參考價值，感興趣的小伙伴們一定要看完！

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)

In Connection.php line 452:

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

二、解決方案

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;

class CreateAdminTable extends Migration
{
  /**

   *
   * @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) {

    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->timestamps();
    });

    Schema::connection($connection)->create(config('admin.database.user_permissions_table'), function (Blueprint $table) {
      $table->integer('user_id');

    });

    });
  }

  /**
   * Reverse the migrations.

   */
  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:install
Migrating: 2016_01_04_173148_create_admin_table
Migrated: 2016_01_04_173148_create_admin_table
