OSX 改变PHP安装路径环境变量

当使用XAMPP来学习Laravel的时候，用composer安装laravel总是报错，说mcrypt is required ，但是当我在终端里打印 which php 显示的是usr/bin/php 没有用XAMPP安装的PHP，所以要改成使用XAMPP中的PHP版本，做法如下：

To those that uses XAMPP 1.7.3 and Mac

Go to Terminal

Enter

which
php

If it says /usr/bin/php, then proceed to 3.

Enter

sudo
nano ~/.bash_profile

(or

sudo
vim ~/.bash_profile

if you know how to use it)

Then paste this

export
PATH="/Applications/XAMPP/xamppfiles/bin:$PATH"

Ctrl - O then enter to save, then ctrl - X to exit.

Type cd ~

type . .bash_profile

restart terminal.

Enter

which
php

Good luck
