When I try to connect to sybase DB I get this error: could not find driver.
Any ideea whats going on? My configuration is:

        'sybaseuepg-aluno' => [
            'driver'   => 'sqlsrv',
            'host'     => env('DB_HOST', 'host'),
            'port'     => env('DB_PORT', '35355'),
            'database' => env('DB_DATABASE', 'mydatabase'),
            'username' => env('DB_USERNAME', 'forge'),
            'password' => env('DB_PASSWORD', 'secret'),
            'charset'  => 'utf8',
            'prefix'   => '',
