Question

尝试运行Illuminate\Database\QueryException : could not find driver时，我遇到php artisan migrate错误。

我环顾四周但找不到这个例外的解决方案。

我在Windows计算机上运行带有PHP 7.2和MySQL 5.7的Laravel 5.6。

这是.env文件：

DB_CONNECTION=mysql
DB_HOST=127.0.0.1 
DB_PORT=3306 
DB_DATABASE=larabiz
DB_USERNAME=root 
DB_PASSWORD=root

还有详细的错误日志：

php artisan migrate -v

   Illuminate\Database\QueryException  : could not find driver (SQL: select * from information_schema.tables where table_schema = larabiz and table_name = migrations)

  at C:\Users\Cyril\Projects\larabiz\vendor\laravel\framework\src\Illuminate\Database\Connection.php: 664
    660|         // If an exception occurs when attempting to run a query, we'll format the error
    661|         // message to include the bindings with SQL, which will make this exception a
    662|         // lot more helpful to the developer instead of just the database's errors.
    663|         catch (Exception $e) {
  > 664|             throw new QueryException(
    665|                 $query, $this->prepareBindings($bindings), $e
    666|             );
    667|         }
    668|

我在Ubuntu 16.04中有一个类似的问题，对我有帮助的是我为php 7.2安装了php-mysql。如果您拥有php 7.2或根据您的PHP版本安装php mysql，我建议您运行以下命令

apt-get install php7.2-mysql

systemctl restart apache2

php artisan migrate错误找不到驱动程序
