Ruby 和 RVM 版本显示不正确

Question

当我从我的 ubuntu 12.04 终端运行 ruby -v 时，我得到 ruby​​ 2.1.1p76(2014-02-24 修订版 45161)[i686-linux]。但是当我通过这个命令指定 rvm 使用 ruby​​ 2.1.1 时 rvm use 2.1.1 我得到这个输出 --> `

tamim@tamim-K43E:/media/Software/git/regexper$ rvm use ruby 2.1.1p76
ruby-2.0.0-p247 is not installed.
To install do: 'rvm install ruby-2.0.0-p247'

RVM is not a function, selecting rubies with 'rvm use ...' will not work.

You need to change your terminal emulator preferences to allow login shell.
Sometimes it is required to use `/bin/bash --login` as the command.
Please visit https://rvm.io/integration/gnome-terminal/ for a example.

`我是 ruby​​ 的新手，以前从未接触过它，只是用它来安装软件。

    tamim@tamim-K43E:/media/Software/git/regexper$ rvm -v
ruby-2.0.0-p247 is not installed.
To install do: 'rvm install ruby-2.0.0-p247'
