I have deleted my entire vendor folder and tried to reinstate it, and it always gets to here and blows up with the same error.

Here is my version pulled from the file, since I can't run an artisan --version to get it for you.
/**
* The Laravel framework version.
*
* #var string
*/
const VERSION = '5.2.32';
Just looking for any help you can give me. This has happened on both my local copy and the site copy

Answer 1

The problem came from having the command
$this->argument in the contructor and not in the handle method.
I just never expected that a console file would stop php artisan --version from stopping to work because of a command file that was not going to be run yet.
Thanks btl for getting me on the right direction.

Answer 2

You have an error in your code somewhere most likely which is giving you this error. Do a global search on getArgument() and see where it can be coming from.
