Rubyonrails Ruby 安装的 RVM 不工作

我使用RVM网站上提到的单一指令安装了RVM(使用git).

然后我安装了Ruby版本1.9.2和1.8.7，使用:

rvm install 1.9.2
rvm install 1.8.7

但是，我找不到Ruby二进制文件.当我try 执行该命令时，会出现以下错误:

[root@server1 support]# rvm use 1.9.2
Using /usr/local/rvm/gems/ruby-1.9.2-p136

[root@server1 support]# ruby
-bash: ruby: command not found

以下是rvm info的输出:

[root@server1 support]# rvm info
