Driver not found when calling "doctrine create-db"

I didn't know why but, I'm not able to perform this command with doctrine create-db . As you can see, my pdo and pdo_mysql is activated.

What code are you trying to run? can you submit it? did you get the above error from /var/log/ inspection?

What happens if you try to run the test code for doctrine:

<?php

// test.php

require 'lib/Doctrine/Common/ClassLoader.php';

$classLoader = new \Doctrine\Common\ClassLoader();
$classLoader->setBasePath('Doctrine', __DIR__ . '/lib');
?>
