【问题描述】：

刚开始探索 Laravel。

我从一开始就创建了一个新项目。尝试运行 php artisan migrate 命令时出现此错误：

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

  at C:\xampp\htdocs\TestLaravelApp\vendor\laravel\framework\src\Illuminate\Database\Connection.php:665
    661|         // If an exception occurs when attempting to run a query, we'll format the error
    662|         // message to include the bindings with SQL, which will make this exception a
    663|         // lot more helpful to the developer instead of just the database's errors.
    664|   



    catch (Exception $e) {
  > 665|             throw new QueryException(
    666|                 $query, $this->prepareBindings($bindings), $e
    667|             );
    668|         }
669| 

  Exception trace:

  1   PDOException::("could not find driver")

我已经尝试了 stackoverflow 中所有可能的解决方案。

可能是我错过了什么。

我正在使用的 php.ini 文件的 URL：https://stackblitz.com/edit/angular-ptnqax

谢谢

【问题讨论】：

检查您的phpinfo 是否实际启用了 PDO MySQL 驱动程序。
已启用....
stackoverflow.com/questions/2852748/…
您已共享 php 7.1 的 phpinfo，但您的 cli php 是 7.3。很有可能您使用的版本与您配置的版本不同，
是的，这就是问题恢复我在 php 安装位置对 .ini 文件所做的更改对我有用。我刚开始使用 laravel 时，不知道为什么要投反对票

标签： php laravel pdo

【解决方案1】：

终于能够弄清楚我的自我了。在更改 xampp 文件夹中的 php.ini 文件中的配置时，我还修改了 php 安装位置 .ini 文件中的文件。恢复所做的更改。

【讨论】：

【解决方案2】：

您需要有一个名为pdo_mysql 的模块。签入php.ini文件

尝试从php.ini 取消注释此行。只需从该行保存文件中删除 ; 并重新启动您的服务器。

 extension=pdo_mysql

尝试在php.ini 文件中添加这一行

 extension=php_pdo_mysql.so

【讨论】：

[Pdo_mysql] ;如果使用 mysqlnd：内部结果集缓存的缓存槽数； php.net/pdo_mysql.cache_sizepdo_mysql.cache_size=2000；本地 MySQL 连接的默认套接字名称。如果为空，则使用内置的 ; MySQL 默认值。 ; php.net/pdo_mysql.default-socketpdo_mysql.default_socket=
是这个人吗
@Amit 你在用 xampp 吗？
@Prashant 是的。 Xampp
@Amit 然后从 xampp 控制面板您可以在apache 选项的config 选项卡上找到php.ini 文件。您只需单击该选项即可。
