joms@Joms-PC:/var/lib$ rvm -v
rvm 1.6.9 by Wayne E. Seguin (wayneeseguin@gmail.com) [https://rvm.beginrescueend.com/]
joms@Joms-PC:/var/lib$ rvm install ruby
ERROR: rvm X,Y,Z 'error' must be followed by arguments. ( see: 'rvm usage' )

Please Help to resolve the issue

Answer 1

You Probably should determine the version of Ruby you wish to install.

use: rvm list known to view the available options, and based on that run something like:

rvm install 2.1

Answer 2

使用脚本像这样或这样在安装系统后安装Ruby和回报率
