I'm a total newbie when it comes to using Terminal, so I don't really understand what's happening here when I try to upgrade my ruby version (1.8.7) with rvm on a Mac OS X 10.7.3.

When I input

rvm install current && rvm use current

I get this

system
system

What does this mean? And how can I proceed with the installation of the latest version?

rvmcurrent命令输出当前激活的 Ruby 安装的名称；在这种情况下，它使用的是系统预装的 Ruby (1.8.7)。

尝试这个：

rvm install 2.0 # (or whatever version you need)
rvm use 2.0 --default # this sets the default to the 2.0 install
