Php 异常“yii\db\Exception”，消息为“找不到驱动程序”

我刚刚在LinuxMint18.2上安装了Yi2.0Advanced，使用的是适用于Linux7.0.23的XAMPP，我的php yii migrate/up命令不起作用。它表明：

with message 'could not find driver'

in /opt/lampp/htdocs/yii/vendor/yiisoft/yii2/db/Connection.php:584

我用谷歌搜索了一下，得到了好几个结果。在那里，我读到“使用php-m命令”；您将了解您的系统使用了哪些php。但我不知道在运行命令后预期的输出是什么

 with message 'could not find driver'

in /opt/lampp/htdocs/yii/vendor/yiisoft/yii2/db/Connection.php:584

您需要安装pdo_mysql模块

然后检查你的phpinfo

我也犯了这个错误。pdo_mysql驱动程序已安装并在phpinfo中显示，web应用程序运行良好，但在命令行中找不到驱动程序。解决方案是提供php版本

cd /var/www/html/project_folder
php7.1 application/yii.php controller/method

先生，我是Yii2.0 advanced的新手。很抱歉，我问了一个愚蠢的问题：如何检查phpinfo意味着从哪里检查？什么？不客气

cd /var/www/html/project_folder
php7.1 application/yii.php controller/method
