我想将MySQL数据库连接到Laravel应用程序。
我使用MySQL的PHPMyAdmin管理工具创建了一个，然后将其添加到.env中，作为database.php应用程序文件。
我运行终端命令：php artisan migrate，它给了我以下错误：

could not find driver (SQL: select * from information_schema.tables where table_schema = pl_project and table_name = migrations and table_type = 'BASE TABLE')
  at C:\Users\u\Documents\pl_project_test\pl_project_test\vendor\laravel\framework\src\Illuminate\Database\Connection.php:760
    756▕         // If an exception occurs when attempting to run a query, we'll format the error
    757▕         // message to include the bindings with SQL, which will make this exception a

以下是我编辑的.env摘录：

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

以下是我编辑的database.php摘录：

'mysql' => [
            'driver' => 'mysql',
            'url' => env('DATABASE_URL'),
            'host' => env('DB_HOST', '127.0.0.1'),
            'port' => env('DB_PORT', '3306'),
            'database' => env('DB_DATABASE', 'pl_project'),
            'username' => env('DB_USERNAME', 'root'),
            'password' => env('DB_PASSWORD', ''),
            'unix_socket' => env('DB_SOCKET', ''),
            'charset' => 'utf8mb4',
            'collation' => 'utf8mb4_unicode_ci',
            'prefix' => '',
            'prefix_indexes' => true,
            'strict' => true,
            'engine' => null,
            'options' => extension_loaded('pdo_mysql') ? array_filter([
                PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
            ]) : [],
        ]

以下是命令的输出：php -m

几点注意事项：

1.我确实向我的 env 变量和MySQL添加了PHP。
1.我在php.ini中取消了对extension=pdo_mysql的注解。
但这一切都没有改变什么，我仍然得到同样的错误。
