Please specify the steps you've performed for Mink installing and the code you're using to run Mink.

Also, have you been able to perform the Composer Install step?

from mink.

1. I installed with composer: composer require behat/mink
2. I ran the usage example code

from mink.

Have you included the Composer autoload.php file ? https://getcomposer.org/doc/01-basic-usage.md#autoloading

from mink.

Yes, of course. Before the usage example code, I wrote the line include_once("path_to_mink_folder/vendor/autoload.php");

from mink.

Had the same problem. Unfortunately, Mink comes WITHOUT a default driver installed. Annoying, but easy to fix.
