在执行gem install redis时,报错:


gem install redis
ERROR:Error installing redis:
redis requires Ruby version >= 2.2.2.这句话的意思是,安装redis需要ruby版本最低是2.2.2,而centos yum库中ruby版本支持到2.0.0。所以,无法满足需求。

1、安装RVM


gpg2 --keyserver hkp://keys.gnupg.net --recv-keys D39DC0E3
curl -L get.rvm.io | bash -s stable
find / -name rvm -print


2、查看rvm库中已知的ruby版本


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[.6]
[ruby-]2.3[.3]
[ruby-]2.4[.0]
ruby-head


3、安装一个ruby版本


rvm install 2.3.3No checksum for downloaded archive, recording checksum in user configuration.ruby-2.3.3 - #extracting rubygems-2.6.12….
ruby-2.3.3 - #removing old rubygems………
ruby-2.3.3 - #installing rubygems-2.6.12…………………….

ruby-2.3.3 - #adjusting #shebangs for (gem irb erb ri rdoc testrb rake).
Install of ruby-2.3.3 - #complete
Ruby was built without documentation, to build it run: rvm docs generate-ri4、使用一个ruby版本
rvm use 2.3.3Using /usr/local/rvm/gems/ruby-2.3.3
5、设置默认版本


rvm use 2.3.3 --defaultUsing /usr/local/rvm/gems/ruby-2.3.3
6、卸载一个已知版本


rvm remove 2.0.07、查看ruby版本
ruby --versionruby 2.3.3p222 (2016-11-21 revision 56859) [x86_64-linux]


8、安装redis


gem install redisFetching: redis-4.0.1.gem (100%)
Successfully installed redis-4.0.1
Parsing documentation for redis-4.0.1
Installing ri documentation for redis-4.0.1
Done installing documentation for redis after 0 seconds

完成!!!
