Updating RubyGems on OS X

I just took a peek at the Ruby on Rails site and version 2.2 is almost out. Since I haven’t been using Ruby or Rails in a while I’ve noticed a lot of changes, so I think I’m gonna start playing with it again – specially since version 2.2 includes i18n, which is what I’ve been waiting for.

So, according to Rails’ creator, I need RubyGems 1.3.1 so I can start playing with Rails 2.2 RC2. Ok, I don’t have a problem with that. Let’s update RubyGems:

$ sudo gem update –system
Updating RubyGems
Bulk updating Gem source index for: http://gems.rubyforge.org/
Nothing to update

Hmm. I’m pretty sure I don’t have the newest version, but I’ll check anyway just in case.

$ gem -v
1.1.1

I thought so. So how come I can’t update? After doing a google search I found I had to try this:

$ sudo gem install rubygems-update
Bulk updating Gem source index for: http://gems.rubyforge.org/
Successfully installed rubygems-update-1.3.1
1 gem installed

$ sudo update_rubygems
…
RubyGems installed the following executables:
        /usr/local/bin/gem
If `gem` was installed by a previous RubyGems installation, you may need
to remove it by hand. 

Let’s just do a quick check:

$ gem -v
1.3.1

There we go! Now we’re ready for Rails 2.2 RC2.
