Having Trouble Updating to Latest RubyGems on the Mac? Try This.

I wanted to install the official release of Merb 1.0 but found I needed to have RubyGems 1.3 installed to do so, no big deal right? Well, on my MacBook Pro running 10.5, I found running the usual command to update RubyGems:

$ sudo gem update –system

Gave me the following:

Updating RubyGems
Updating rubygems-update
Successfully installed rubygems-update-1.3.0
ERROR: While executing gem … (NameError)
undefined local variable or method `remote_gemspecs’ for #
$ gem –version
1.2.0

Thinking I had typed something wrong because updating RubyGems always works, I tried again only to see this:

$ sudo gem update –system
Updating RubyGems
Nothing to update
$ gem –version
1.2.0

A bit of searching around the web I found a blog with a post matching my exact problem with a solution that worked perfectly from Wincent.com. I then proceeded to install Merb and now have Merb 1.0 installed.
