The help has a load of different options. I tried:
composer global require "laravel/installer=~1.1"
which returns:
[RuntimeException]
Not enough arguments.
And then there is a load of articles referencing the windows installer located at:
http://laravel.com/laravel.phar
Which says: "Whoops, looks like something went wrong."
I'm not sure what else to try? Am I missing something?
