使用rvm方式在centos7.5上安装ruby

依次执行：

gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB
curl -sSL https://get.rvm.io | bash -s stable  #如果下载不下来https://get.rvm.io，可先访问复制脚本到rvm.sh，再cat rvm.sh|bash -s stable
source /etc/profile.d/rvm.sh
rvm list known #查看版本
rvm install 2.4.9 #安装ruby
ruby -v
gem install sass  #安装sass
gem install compass  #安装compass
sass -v
compass -v

之前尝试用其他方式安装ruby，但是 gem install sass 安装报错，如下。

yum -y install ruby ruby-devel rubygems rpm-build  
ruby -v
ruby 2.0.0  版本过低安装不上sass
升级：
yum install -y centos-release-scl-rh
yum install -y rh-ruby23
scl enable rh-ruby23 bash
[root@localhost ~]# ruby -v
ruby 2.3.5p335 

此时安装 sass会报错

[root@one huan_yang]# gem install sass

ERROR:  Error installing sass:

安装ruby与compass sass环境
