Uncaught Error: Class 'Symfony\CS\Config\Config' not found

I've been struggling with this all day. I got brought in to a new app and they require php-cs-fixer to be ran on all files. The project has a .php_cs file in it, but I couldn't get it work in sublime text 3 nor could I get vscode to do it.

The command runs but I get the error:

PHP Fatal error:  Uncaught Error: Class 'Symfony\CS\Config\Config' not found in C:\dev\code\.php_cs:63

Here is the .php_cs file

I can run the file manually by going to the cmd prompt and running

php-cs-fixer fix .\Controller.php

And it does what it's supposed to, I think with a default .php_cs file. Driving me bats. :)

Problem is we were trying to use an older version of php-cs-fixer and it didn't function correctly with our version of php.

Fix was to update to php-cs-fixer v2.*
