我正在使用ubuntu 11.10而且我在安装ruby时遇到了麻烦。当我试图安装它时，它给出了这个：
Installing Ruby from source to: /usr/share/ruby-rvm/rubies/ruby-1.9.3-p125, this may take a while depending on your cpu(s)...

之后我测试了ruby并返回：
The program 'ruby' can be found in the following packages:
* ruby1.8
* ruby1.9.1
Try: sudo apt-get install <selected package>
请帮忙。

我之前也遇到过这个问题。它失败的原因是缺乏依赖包。
运行rvm requirements，查看要求并安装所有软件包，包括ruby-head
对我来说，我必须安装：
sudo apt-get install curl patch build-essential openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion
运行所有软件包后，键入以下命令安装1.9.3或Rubinius：
rvm install 1.9.3或rvm install rbx
应该顺利进行。
安装完成后，转到终端 - >编辑 - ＆gt;配置文件首选项 - ＆gt;标题和命令，选中Run command as login shell。关闭，关闭终端窗口。打开一个新的终端窗口，运行rvm --default use 1.9.3（或其他），然后再次关闭终端。
现在打开一个新的终端，键入ruby，它现在应该给你正确的红宝石。
