解决Centos7 安装sklearn gcc: error: ‘-Qunused-arguments’
时间:2016-09-06 16:51 来源:linux.it.net.cn 作者:IT
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
下载：
