yum install gcc-c++: Nothing to do Package gcc-c++ already installed and latest

系统为centos7,在安装wget时,执行命令:yum -y install gcc-c++,提示如下错误:

Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
 * base: mirrors.aliyun.com
 * extras: mirrors.aliyun.com
 * updates: mirrors.aliyun.com
Package gcc-c++-4.8.5-39.el7.x86_64 already installed and latest version
Nothing to do

根据提示猜测是,gcc-c++已经安装但没有正常启动,所以就先删除再重新安装,删除执行如下:

yum remove gcc-4.8.5-39.el7.x86_64
执行成功后,再执行安装gcc-c++操作,命令如下:

yum -y install gcc-c++
安装成功,如下:
