centos7 安装软件报错 psutil installation failed
缺少gcc环境
yum install gcc gcc-c++ gcc-g77
用yum install gcc 安装不上 显示noting to do
更换yum源
cd /etc/yum.repos.d
备份以下原来系统中的yum源文件
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
或
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
添加EPEL
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
执行如下清除命令
yum clean all
yum makecache
再运行yum install gcc gcc-c++ gcc-g77
OK,可以了
