Question: Whenever I run any `php artisan` command like `php artisan list`, I get nothing back. No commands work at all.

I have been searching a little around, and have tried the following:

* changing permissions for `/root/.composer` to 777
* remove `bootstrap/compiled.php` file

There is nothing in `app/storage/logs/log-cli-.txt`.  

I can view the site in the browser.

I'm running on CentOS 6.3 64bit with PHP v. 5.5.11 - Laravel 4.1

Answer: 
This problem is pretty common and is usually related to some errors that are not seen in the CLI like custom classes that failed to load, are you sure you have error reporting on?

Edit the file `artisan` and add the following lines just after the PHP opening tag `<?php`:

```
ini_set('display_errors',1);
error_reporting(-1);

```

Try running `artisan` again and see if there is any output.

If that doesn't work try reverting `app/start/global.php` to it's default state.
Running `composer install` solved the problem.
