Question

我刚刚在linux mint 18.2上安装了yii2.0高级版，使用XAMPP for Linux 7.0.23，我的php yii migrate / up命令不起作用。它显示：

with message 'could not find driver'

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

我用谷歌搜索了它，我得到了几个结果。在那里，我读了＆＃39;使用php -m命令＆＃39 ;;你会发现你的系统使用过哪个php。但是我不知道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

Answer 1

您需要安装pdo_mysql模块。

sudo apt-get install php-mysql

之后检查phpinfo();

Answer 2

我也遇到了这个错误。 pdo_mysql 驱动程序已安装并显示在 phpinfo() 中，Web 应用程序运行良好，但从命令行找不到驱动程序。解决办法是提供php版本

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

例外＆＃39; yii \ db \ Exception＆＃39;有消息＆＃39;无法找到驱动程序＆＃39;
