使用codeigniter实现php activerecord时出现的问题

我正试图根据我在上一篇stackoverflow文章中遇到的问题来实现php活动记录

好的，我把代码放到构造函数中，我的错误就消失了

但现在我们来测试orm是否有效。我使用以下代码在models文件夹中创建了名为User.php的模型

<?php

class User extends ActiveRecord\Model {


}  

?> 

此外，my database.php配置为与表匹配，如下所示：

$db['default'] = array(
    'dsn'   => '',
    'hostname' => 'localhost',
    'username' => 'root',
    'password' => '',
    'database' => 'spark',
    'dbdriver' => 'mysqli',
    'dbprefix' => '',
    'pconnect' => TRUE,
    'db_debug' => TRUE,
    'cache_on' => FALSE,
    'cachedir' => '',
    'char_set' => 'utf8',
    'dbcollat' => 'utf8_general_ci',
    'swap_pre' => '',
    'autoinit' => TRUE,
    'encrypt' => FALSE,
    'compress' => FALSE,
    'stricton' => FALSE,
    'failover' => array()
);

dats对数据库进行了排序，因此我打开了welcome.php控制器，并将以下代码添加到index方法中，如下所示

public function index()
    {


        $users = User::all();

        echo "<pre>";
        print_r($users);
    }  

所以人们让我知道我认为问题出在哪里

谢谢

异常消息清楚地显示了问题：

消息：未捕获异常“ActiveRecord\DatabaseException”，消息“未找到ActiveRecord\MysqliAdapter！”在C:\xampp\htdocs\orm\sparks\php-activerecord\0.0.2\vendor\php中-

它试图为ActiveRecord库加载mysqli适配器，但找不到它。要么库未完全安装（可能缺少可选的mysqli模块），要么包含路径未正确设置以自动加载其类。

我只是想通过composer安装active record，以便能够正确自动加载。您解决了吗？在升级Codeigniter版本时，我也面临同样的问题

public function index()
    {


        $users = User::all();

        echo "<pre>";
        print_r($users);
    }
