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:
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): //具体RVM安装命令地址:http://rvm.io/ [root@linux ~]# gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB [root@linux ~]# curl -sSL https://get.rvm.io | bash -s stable [root@linux ~]# find / -name rvm -print /usr/local/rvm [root@linux ~]# source /usr/local/rvm/scripts/rvm 2、查看rvm库中已知的ruby版本: [root@linux ~]# rvm list known MRI Rubies [ruby-]1.8.6[-p420] [ruby-]1.8.7[-head] # security released on head [ruby-]1.9.1[-p431] [ruby-]1.9.2[-p330] [ruby-]1.9.3[-p551] [ruby-]2.0.0[-p648] [ruby-]2.1[.10] [ruby-]2.2[.7] [ruby-]2.3[.4] [ruby-]2.4[.1] ruby-head …. 3、安装一个ruby版本: [root@linux ~]# rvm install 2.4.1 Searching for binary rubies, this might take some time.
