I just recently started getting back into Rails now that the new Agile Web Development with Rails book (3rd edition) came out. I had an old, out-of-date installation of ruby and gem so I tried to follow the advice found at: <http://blog.carlmercier.com/2007/12/14/how-to-fix-that-rubygems-mess-on-leopard/> which recommended completely removing the Apple installed ruby and gem. After doing so, I then installed using MacPort per the instructions. Installation went okay until attempting to update Rubygems per this command: sudo gem update --system This resulted in an error: /opt/local/bin/gem:14: undefined method `ruby_version'' for Gem:Module (NoMethodError) I googled for a solution and found this solution: <http://cristian.livadaru.net/2008/07/22/how-to-solve-undefined-method-ruby_version-for-gemmodule-nomethoderror-on-os-x/> However after trying that solution I got yet another error:> gem install -l rubygems-update-1.2.0.gem/opt/local/lib/ruby/site_ruby/1.8/rubygems/gem_runner.rb:18:in `initialize'': uninitialized constant Gem::CommandManager (NameError) from /opt/local/bin/gem:24:in `new'' from /opt/local/bin/gem:24 So I am wondering: Why is it so (apparently) difficult to update ruby and gem on Mac OS X? Is it just me? Or others having this same problem? This struggle to get ruby and gem up to date seems antithetical to the ease with which rails in general seems to work. This kind of makes me wish for an ''Instant Rails'' solution for Mac OS X! Does anyone here have an up-to-date solution for installing ruby 1.8.7 and gem 1.3.1 from scratch on Mac OS X that works?

I''ve had no problems with the Apple-supplied Ruby on Leopard. (Things were different on Tiger.)> This kind of makes me wish for an > ''Instant Rails'' solution for Mac OS X!You shouldn''t need it on Leopard, but try Locomotive. It was designed for Tiger, but I believe it still works.> > Does anyone here have an up-to-date solution for installing ruby 1.8.7 > and > gem 1.3.1 from scratch on Mac OS X that works?Yes. Just use Apple''s versions and upgrade as necessary. :)> > TIA!Best, -- Marnen Laibow-Koser marnen-sbuyVjPbboAdnm+yROfE0A@public.gmane.org http://www.marnen.org -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

You didn''t need to uninstall Apple''s ruby and gems. Simply install your own in a separate folder and then edit your PATH variable to tell the system where to look for. What''s the output of $ ruby -v ? is it as expected? -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
