I've spent quite a lot of time playing around and couldn't find any documentation on this problem, I will be honest and say I don't know enough about composer to solve it.

EDIT

I tried the following which was suggested in the answers, without any luck.

ubuntu@ip-10-252-31-19:/home/user$ sudo composer create-project laravel/laravel master

Answer 1

I had the same issue lately. Just run composer with --no-scripts flag.

composer update --no-scripts
