出现的问题:

[root@localhost ~]# gem install redis

Fetching: redis-4.0.1.gem (100%)

ERROR: Error installing redis:

redis requires Ruby version >= 2.2.2.

原因:ruby版本太低,要求2.2.2版本+

解决:安装rbuy高版本

需要用rvm 来安装ruby[root@localhost ~]# gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3

Creating group 'rvm'

Installing RVM to /usr/local/rvm/

Installation of RVM in /usr/local/rvm/ is almost complete:

* First you need to add all users that will be using rvm to 'rvm' group,

and logout - login again, anyone using rvm will be operating with `umask u=rwx,g=rwx,o=rx`.

* To start using RVM you need to run `source /etc/profile.d/rvm.sh`

in all your open shell windows, in rare cases you need to reopen all shell windows.

[root@localhost ~]# source /etc/profile.d/rvm.sh

[root@localhost ~]# rvm -v
