这是由于OS X El Capitan发行时已经安装了六个1.4.1，当它试图卸载它时（由于awscli依赖于botocore，botocore依赖于python-dateutil，python-dateutil依赖于六> = 1.5）由于系统完整性保护甚至不容许root修改这些目录。

理想状况下，点应该跳过卸载这些项目，由于他们没有安装到他们安装到一个特殊的苹果目录的网站包。可是，即便点击跳过卸载这些项目，并安装六个站点包，咱们会遇到另外一个错误，苹果把他们预先安装的东西早于sys.path站点包。

解决办法：

➜  /test sudo pip install --ignore-installed six
