Unexpected Laravel 5 errors using Vagrant

Question

I'm usign a project structure using vagrant + puppet + capistrano + Laravel 5 for my API and I was working very well deploying from my local to the stage for 1 month but suddenly from yesterday I can't execute my local environment.

When I up my vagrant machine doesn't show any error and I already deleted the box, the instance, re-installed VirtualBox and Vagrant and still the same error and the weirdest thing is in other computer works fine with no issues.

The error always happens when I update/install with composer in "Generating autoload files"

I've reinstalled many times and still the same error.

VirtualBox: 4.3.28
Laravel: 5.0.22

Answer 1

Do you have .dotenv file in your project? If so please check whether you have consistent end of lines (unix/windows/mac).

Answer 2

You should check the .env file, or better remake it using your favourite IDE. DotEnv.php line 51 tries to strip the comments from the .env file and there's an encoding error in your file.
