今天在做Redis的Cluster集群的时候，在执行gem install redis时，提示如下错误：
gem install redis
ERROR: Error installing redis:
redis requires Ruby version >= 2.2.2.
CentOS7 yum库中ruby的版本支持到 2.0.0，可gem 安装redis需要最低是2.2.2，采用rvm来更新ruby：
1、安装RVM（具体命令可以查看官网，Ruby官网地址 和 Ruby官网安装教程）：

4、使用一个ruby版本：
|
1
2
|
[root@linux ~]# rvm use 2.4.1 Using /usr/local/rvm/gems/ruby-2.4.1 |
5、设置默认版本：(设置ruby2.4.1为默认的ruby，因为还安装有1.8.3)
|

2
|
[root@linux ~]# rvm use 2.4.1 --default Using /usr/local/rvm/gems/ruby-2.4.1 |
6、卸载一个已知版本：
|
1
|
[root@linux ~]# rvm remove 2.3.4 |
7、查看ruby版本：
|
1
2
|
[root@linux ~]# ruby --versionruby 2.4.1p111 (2017-03-22 revision 58053) [x86_64-linux] |
8、安装redis：

问题解决，不错，过了年就解决了一个问题，还是值得庆祝的。
