Mysql 连接，但 Mysqli 未显示文件或目录错误

Question

更新我的 myqsli 驱动程序函数后，我一直看到这个

     A PHP Error was encountered
    Severity: Warning
    Message: mysqli_connect(): (HY000/2002): No such file or directory
    Filename: mysqli/mysqli_driver.php
    Line Number: 110
    Backtrace:
    File: /Applications/XAMPP/xamppfiles/htdocs/alcantara/application/controllers/Vendor.php
    Line: 11
Function: __construct
File: /Applications/XAMPP/xamppfiles/htdocs/alcantara/index.php
Line: 274
Function: require_once

我不知道我是否需要再次安装任何东西，我正在使用mac os。这是我的数据库文件

*/
$active_group = 'default';
$query_builder = TRUE;
$db['default']['hostname'] = '127.0.0.1';
$db['default']['username'] = 'testing';
$db['default']['password'] = '';
$db['default']['database'] = 'database';
$db['default']['dbdriver'] = 'mysqli';
$db['default']['dbprefix'] = '';
$db['default']['pconnect'] = FALSE;
$db['default']['db_debug'] = TRUE;
$db['default']['cache_on'] = FALSE;

$db['default']['swap_pre'] = '';
$db['default']['autoinit'] = TRUE;
$db['default']['stricton'] = FALSE;
$db['default']['socket'] = 'mysql:unix_socket=/cloudsql/project_id:xxx';

我终于解决了它，购买更新我的代码点火器mysqli连接功能，使用我从网站下载的新功能。
