ruby - rvm 系统安装，bin 未正确符号链接(symbolic link)

Question

我在 ubuntu 12.04 上并安装了 rvm 系统范围:$ \curl -L https://get.rvm.io | sudo bash -s stable
到目前为止，我一直执行单用户安装，老实说，我对系统范围安装的结果感到非常困惑。
它确实将 rvm bin 目录放在了我的路径中，但它用无法直接使用的名称符号链接(symbolic link)了所有二进制文件。
这是否意味着我应该一个一个地对它们进行符号链接(symbolic link)？
出事了吗？
这是默认行为吗？

The program 'ruby' can be found in the following packages:
 * ruby1.8
 * ruby1.9.1
Ask your administrator to install one of them

你应该检查/usr/local/rvm/wrappers尤其是 /usr/local/rvm/wrappers/default对于可以从 PATH 使用的二进制文件环境中没有其他设置。
