**环境描述：**

操作系统：CentOS Linux release 7.5

Redis版本：3.2.5  64 bit

Redis集群节点：6个

**1、安装redis集群时报如下错误：**

/usr/share/rubygems/rubygems/core\_ext/kernel\_require.rb:55:in \`require': cannot load such file -- redis (LoadError)  
    from /usr/share/rubygems/rubygems/core\_ext/kernel\_require.rb:55:in \`require'  
    from ./redis-trib.rb:25:in \`<main>'

**2、解决办法：**

Ruby的redis接口没有安装，需要安装Redis接口，输入命令 " gem install redis " 进行安装，如下：

\[root@localhost redis-cluster\]\# gem install redis  
Fetching: redis-4.1.0.gem (100%)  
ERROR:  Error installing redis:  
    redis requires Ruby version >= 2.2.2.

**3、在安装Redis接口的时候可能会遇到如上的问题，以上错误信息告诉我们Ruby版本太低**

关于Ruby 版本过低低的办法参考[《 如何升级ruby的版本 》][_ruby_]

**4、解决 Ruby 版本的需求后，输入命令 " gem install redis " 进行 Redis 接口安装，如下：**

\[root@localhost ~\]\# gem install redis  
Fetching: redis-4.1.0.gem (100%)  
Successfully installed redis-4.1.0  
Parsing documentation for redis-4.1.0  
Installing ri documentation for redis-4.1.0  
Done installing documentation for redis after 1 seconds  
1 gem installed

解决好ruyb版本以及redis接口后，就可以正常安装redis集群
