使用 RVM 安装 Ruby 1.9.2 不起作用

Question

当我执行 >rvm install 1.9.2 时，一切顺利。然后我使用 >rvm use 1.9.2，这也很顺利。

不过，当谈到 ruby​​ -v 时..

sam@sjones:~$ rvm install 1.9.2
/home/sam/.rvm/rubies/ruby-1.9.2-p136, this may take a while depending on your cpu(s)...

Using /home/sam/.rvm/gems/ruby-1.9.2-p136
sam@sjones:~$ ruby -v
-bash: ruby: command not found

我到底该怎么做？我已经尝试了几个小时了

这是我的 rvm 信息输出：

试试这个：

rvm --default use 1.9.2

--EDIT--
问题已解决，您需要运行：
[[ -s "$HOME/.rvm/scripts/rvm" ]] && 。 “$HOME/.rvm/scripts/rvm”
