Laravel Composer安装一直处于失败状态

I'm trying to install Laravel 5.2 using Composer on Windows but it keeps on failing.

C:\wamp\www>composer create-project --prefer-dist laravel/laravel vas

Answer 1

It looks like it's failing on php -r - try running this command manually and see if you get the same error? if you do, it's something to do with your PHP CLI.
