我已经在互联网上搜寻了此问题的答案，但似乎没人能找到它。
因此，我在PHP版本5.6.36和MySQL版本5.6.39上安装了FuelPHP，尝试使用Auth :: create_user（）创建新用户时出现错误。错误如下：
燃料\核心\数据库异常[2014（2014）]： 命令不同步；您现在不能运行此命令
我已经正确配置了所有db.php文件（我相信），因为FuelPHP能够访问我的SQL Server并在其中创建表。这是我的控制器中导致此错误的代码：

在加载索引页时调用load_tables（）函数。 DBUtil :: create_table（）查询执行没有问题，但是当调用Auth :: create_user（）时，它将失败，并出现上述错误。
也：如果我使用在示例中已注释掉的DB：insert（），它将执行而不会出现问题，并将新记录插入表中。但是，我需要使用Auth :: create_user（）才能进行身份验证。
