如何在Linux(Ubuntu)上更新ruby? [英] How to update ruby on linux (ubuntu)?

问题描述

我在ruby和linux上都是新手，所以我确定这是微不足道的，但我还不知道.我目前安装了ruby 1.8.7，我想将其更新为ruby 1.9.我该怎么办?

I'm newbie on both ruby and linux, so I'm sure this is trivial but I don't know yet. I currently have ruby 1.8.7 installed and I want to update it to ruby 1.9. How can I do that?

推荐答案

sudo apt-get install ruby1.9

应该可以解决问题.

您可以找到

apt-cache search <your search term>

所以我只是做了apt-cache search ruby | grep 9来找到它.

So I just did apt-cache search ruby | grep 9 to find it.

您可能需要将新的Ruby调用为ruby1.9，因为如果您键入ruby，Ubuntu可能默认为1.8.

You'll probably need to invoke the new Ruby as ruby1.9, because Ubuntu will probably default to 1.8 if you just type ruby.
