推荐答案

如果没有在机器中本地安装 ruby，您将无法使用 rbenv.您应该安装 ubuntu 的 ruby​​ (sudo apt-get install ruby​​)，这样 rbenv 就会有一个可以使用的基本版本.如果你可以运行 ruby -v 那么你就大功告成了.

You can't use rbenv without a native installation of ruby in the machine. You should install ubuntu's ruby (sudo apt-get install ruby) so rbenv will have a base version to work with. If you can run ruby -v then you're all set.
