允许composer安装laravel 4并检测MAMP'；s的PHP版本不是系统

composer等新手，遇到问题。

当尝试使用下载所有文件时

composer create laravel/laravel laravelNew

我看到这个错误：

Installing laravel/laravel (v4.2.0)
- Installing laravel/laravel (v4.2.0)
Loading from cache

Potential causes:
- A typo in the package name
- The package is not available in a stable-enough version according to your minimum-stability setting

我在安装了PHP 5.3的mac上，这在进行PHP-v 时得到了证实

PHP 5.3.26 (cli) (built: Jul  7 2013 18:30:38) 

然而，我使用MAMP在本地运行我的网站。

有没有一种方法可以让作曲家检查MAMP php版本？由于MAMP PHP版本为5.4+

谢谢。克雷格。
