From: Lostin Ruby Date: 2009-04-24T18:28:24+09:00 Subject: installation trouble?? Hi, I am very new to ruby and have hit a wall with the installation. I am using a Mac OS X 10.4.11(Tiger). I got everything installed correctly (Ruby Version 1.8.6, RubyGems 1.3.2, Rails Version 2.3.2, db adapter sqlite3) and I was trying to work through the Agile Web Development with Rails 2nd edition. There was an issue with scaffold being deprecated in newer versions so I scoured the web to find a fix. I tried to uninstall RubyGems 1.3.2 so that I could work through the book edition 2 with the intention of installing the newer version later. However now when I try to start the server I get the message Rails requires RubyGems >= 1.3.1 (you have 0.9.2). Please `gem update --system` and try again. and when I try to update my gems or indeed run any other gem command I get the error /usr/local/lib/ruby/site_ruby/1.8/rubygems/source_index.rb:92:in `load_specification': private method `specification_version=' called for # (NoMethodError) from /usr/local/lib/ruby/site_ruby/1.8/rubygems/specification.rb:421:in `initialize' from (eval):3:in `new' from (eval):3:in `load_specification' from /usr/local/lib/ruby/site_ruby/1.8/rubygems/source_index.rb:128:in `eval' from /usr/local/lib/ruby/site_ruby/1.8/rubygems/source_index.rb:92:in `load_specification' from /usr/local/lib/ruby/site_ruby/1.8/rubygems/source_index.rb:128:in `load_gems_in' from /usr/local/lib/ruby/site_ruby/1.8/rubygems/source_index.rb:127:in `each' from /usr/local/lib/ruby/site_ruby/1.8/rubygems/source_index.rb:127:in `load_gems_in' ... 14 levels... from /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `gem_original_require' from /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `require' from /usr/local/lib/ruby/site_ruby/1.8/rubygems.rb:112:in `manage_gems' from /usr/local/bin/gem:10 I'm really at a loss so any help would be greatly appreciated. Please bear in mind that I am very new to Macs and Ruby. Kind regards, LostinRuby -- Posted via http://www.ruby-forum.com/.
