laravel pdo_connection mssql

Question

我有laravel 5.6，我需要将它连接到mssql远程。我有db_lib驱动程序。我已经安装了freetds。这些是消息：

PDOException  : SQLSTATE[IM001]: Driver does not support this function: driver does not support that attribute

at /home/agner/Documentos/ubuntu-laravel/vendor/doctrine/dbal/lib/Doctrine/DBAL/Driver/PDOConnection.php:71

public function getServerVersion()
70|     {
 > 71|         return PDO::getAttribute(PDO::ATTR_SERVER_VERSION);
72|     }

Exception trace:

1   PDO::getAttribute()

2 Doctrine\DBAL\Driver\PDOConnection::getServerVersion()
