CentOS 7 安装sklearn gcc: error: ‘-Qunused-arguments’

1. 在CentOS7上安装sklearn各种报错

gcc: error: unrecognized command line option ‘-Qunused-arguments’
gcc: error: unrecognized command line option ‘-Qunused-arguments’
gcc: error: unrecognized command line option ‘-Qunused-arguments’

google下应该是pip版本问题，之前安装的pip版本是7.1，现在最新版本都到8.1了

2. 在pipy下载pip whl安装文件

https://pypi.python.org/pypi/pip下载whl安装文件
