Hello to these programming on Laravel on Windows Environment.
I don't think this will have an easy solution, I will drop it here though.
I am programming using Windows PowerShell as my default terminal. And all of a sudden, working on a Laravel PHP Project, seems that the commands "php artisan" are not working fine.
There's how it looks the command "php artistan list" in my blue PowerShell, and in the normal black Windows CMD:
CMD and powershell:
Using the normal CMD seems to work fine, meanwhile in PowerShell, results do not work fine.
I've reinstalled Composer, tried in Laravel 5.2 & 5.3 versions, and using XAMPP PHP 5.6.15.
Files weren't from Git, were created there.

Powershell doesn't support UNIX ANSI escape sequences (ANSI Color Codes).
Use Windows Command Prompt (CMD.EXE).
Best Regards
