标签：Collecting none whl py2 ipython Mac iPython 安装 any
没有想象中那么顺利，尽管我已经搞定了pip，但是依然还是遇到了问题。安装的时候为了能够让安装顺利，需要使用sudo在管理员模式下安装。不过，为了能够让当前目录使用安装的东西，需要加上-H的参数。
安装操作如下：

Found existing installation: six 1.4.1
DEPRECATION: Uninstalling a distutils installed project (six) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project.

开始看着似乎蛮顺利，没想到到了后面出来一个崩溃性问题。通过提示得知应该是权限问题，但是切换到管理员下面去执行依然还是有这个问题。由此猜测应该是还有一层系统级的保护权限。借助于网络查了好一阵子，终于找到了解决方案，需要取消系统中的SIP机制。之后再次尝试安装，安装成功，具体的过程如下：
