解决方案
pip install --upgrade pip sudo pip install numpy --upgrade --ignore-installed sudo pip install scipy --upgrade --ignore-installed sudo pip install scikit-learn --upgrade --ignore-installed
如果还不能解决的话
1、重启电脑，按command+R进入恢复模式，点击菜单【实用工具】，打开【终端】，输入 csrutil disable
2、重启电脑，正常进入，打开【终端】输入 csrutil status
这是macosx 10.11 EI Capitan使用了Rootlees，可以理解为一个更高等级的内核保护，系统会默认锁定/system , /sbin , /usr这三个目录，
通过上面方法可以将这个保护关闭。
如果没有关闭，安装一些软件时会出现
