What is the stable version of Rubygems for rails 2.3.11?

Question

Now I have rubygems version 1.3.7. I just installed rails 2.3.11 and I want to update my rubigems. What is the stable version of Rubygems for rails 2.3.11.

Answer 1

I am running 2.3.11 with RubyGems 1.7.2 without having to require a "thread" or make any changes to existing Rails code. The 1.8 series is causing problems for me, so I downgraded.

gem uninstall rubygems-update #and choose all versions if asked
gem install rubygems-update -v 1.7.2
update_rubygems
gem -v
  => 1.7.2

Answer 2

This worked fine for me to downgrade from RubyGems 1.8.10 (for Rails 3) to 1.37 (for Rails 2):

gem update --system 1.3.7

Answer 3

1.5.2 2.x.

1.5.3 2.x

1.6.1 has just been released: rubygems-1.6.1 - Rubygems 1.6 has a failure warning for 2.x rails and in changelog

RubyGems no longer requires a thread. Rails <3 need to add require 'thread to your applications.

Do not consider this a big problem, but you may have to add this small requirement to all your 2.x applications if you install 1.6
