Doctrine\DBAL\Driver\PDOException

I keep running into this problem and I have followed all instructions to fix it but it doesn't seem to be working.

I am running Linux Mint and I have run composer update etc with the message of that everything is up to date.

My composer.json also represents that it is there.

"require": { "php": "^7.1.3", "doctrine/dbal": "^2.9", "fideloper/proxy": "^4.0", "laravel/framework": "5.8.*", "laravel/tinker": "^1.0" },

Please please, I am actually at the stage where I am going to uninstall Linux and reinstall windows.
