为什么我不能通过apt-get在Ubuntu上安装ruby 1.9.2？

Question

apt-get install ruby

Installs ruby 1.8.7

When I install ruby 1.9.2 from sources via ./configure make install, ruby is not installed (ruby -v gives nothing).

So how can I install ruby 1.9.2 on Ubuntu?

Answer 1

I use rvm Ruby Version Manager on my ubuntu-10.04.1-desktop. With ruby-1.9.2 , ruby 1.8.7 no problem.

Answer 2

• on 10.10 "Maverick Meerkat": apt-get install ruby1.9.1
• on 10.04 "Lucid Lynx": Ruby 1.9.2 was only released a couple of weeks ago, it didn't exist when Lucid was frozen.

Answer 3

You can also proceed to upgrade the ruby installation, as below,

sudo apt-get upgrade ruby

Answer 4

You can install ruby 1.9.1 with

sudo apt-get install ruby1.9.1

ruby 1.9.2 is not available for lucid (but I have not checked backports).
