database connection could not be established, could not find driver

I am trying to install Gibbion on my local server with MAMP/Xampp and windows 10.
But after putting Database Server->localhost,Database Name->one, Database Username->root,Database Password->root.
it shows the following error.
could not find driver A database connection could not be established
How can i fix this problem.

Thank You

ehsan, Gibbon uses PHP’s PDO class to connect to a MySQL database. In most server stacks this is enabled by default, but it seems that in XAMPP it must be disabled. Check out the instructions here for some advice on how to enable the PDO extension.
