mysql - laravel php artisan 迁移问题

Question

当我运行此命令时:php artisan migrate 我遇到错误:

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

我已经用 ubuntu 18.04 和 PHP、MySQL 7.2 设置了一个 vagrant 环境。我编辑了 php.ini 文件，并在网络上的 100 个站点上完成了所有 1000 件事情。我很困惑它仍然无法迁移

composer create-project laravel/laravel projectname

config/database.php

'mysql' => [
            'driver' => 'mysql',
            'host' => '127.0.0.1',//env('DB_HOST', '127.0.0.1'),
            'port' => '3306',//env('DB_PORT', '3306'),
            'database' => 'loag',//env('DB_DATABASE', 'forge'),
            'username' => 'root',//env('DB_USERNAME', 'forge'),
            'password' => 'root',//env('DB_PASSWORD', ''),
            'unix_socket' => '/etc/mysql/mysql.sock',//env('DB_SOCKET', ''),
            'charset' => 'utf8mb4',
            'collation' => 'utf8mb4_unicode_ci',
            'prefix' => '',
            'prefix_indexes' => true,
            'strict' => true,
            'engine' => null,
        ],

在 ubuntu 上安装:在此处输入代码

# Set environment variable

需要更多？

当我这样做时:php artisan migrate 生成以下输出:

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

  at C:\Users\Marco Ris\Desktop\Webdevelopment\loag\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|
