我正在尝试使用kohana的Auth / ORM模块创建登录/注册页面。我已经成功安装了MySQLi模块，并在bootstrap.php文件中添加了一行。现在，当我尝试创建一个输入了所有详细信息的帐户时，我收到一条错误，指出ErrorException [注意]：尝试获取非对象的属性。 MySQLi.php文件中的67个。我正在使用xampp / phpmyAdmin。
错误符合：＆＃39;：代码＆＃39; =＆GT; $这 - ＆GT; _connection-＆GT; connect_errno，

有一个database.php，您可以在/modules/database/config
您可以在那里填写数据库凭据。
