使用Rails3的第一步安装Ruby1.8.7
$ # 安装gem软件包rvm
$ sudo gem install rvm
$ rvm-install
$ vim ~/.profile #该文件名称不一定每个系统都相同。下面一行代码存放到该文件的最后一行，但是在其后不能够有空行！完成此操作以后，需要打开新的终端，看看是否出现错误。没有错误说明此操作正常。切记：下面的所有操作命令将在新终端窗口进行。
if [[ -s ${HOME}/.rvm/scripts/rvm ]] ; then source ${HOME}/.rvm/scripts/rvm ; fi # 需要增加的代码
$ # 安装Readline
$ rvm package install readline
$ # 安装Ruby 1.8.7
$ rvm install 1.8.7 -C --enable-shared,--with-readline-dir=$HOME/.rvm/usr
$ # 使用Ruby1.8.7切换命令
$ rvm 1.8.7 #打开新的终端还是Ruby 1.8.6
$ which ruby #查看Ruby 1.8.7安装在哪里
