I got the following while attempting to install rails on Ubuntu 6.06 LTS with Ruby 1.8.4:

tim@tim-ubuntu:~/Desktop/rubygems-0.9.0$ sudo gem install rails --include-dependencies Bulk updating Gem source index for: http://gems.rubyforge.org Successfully installed rails-1.1.6 Successfully installed rake-0.7.1 Successfully installed activesupport-1.3.1 Successfully installed activerecord-1.14.4 Successfully installed actionpack-1.12.5 Successfully installed actionmailer-1.2.5 Successfully installed actionwebservice-1.1.6 /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:27:in `gem_original_require': no such file to load -- rdoc/rdoc (LoadError)         from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:27:in `require'         from /usr/local/lib/site_ruby/1.8/rubygems/doc_manager.rb:71:in `load_rdoc'         from /usr/local/lib/site_ruby/1.8/rubygems/doc_manager.rb:41:in `generate_ri'         from /usr/local/lib/site_ruby/1.8/rubygems/gem_commands.rb:283:in `execute'         from /usr/local/lib/site_ruby/1.8/rubygems/gem_commands.rb:282:in `execute'         from /usr/local/lib/site_ruby/1.8/rubygems/gem_commands.rb:220:in `execute'         from /usr/local/lib/site_ruby/1.8/rubygems/command.rb:69:in `invoke'         from /usr/local/lib/site_ruby/1.8/rubygems/cmd_manager.rb:117:in `process_args'         from /usr/local/lib/site_ruby/1.8/rubygems/cmd_manager.rb:88:in `run'         from /usr/local/lib/site_ruby/1.8/rubygems/gem_runner.rb:29:in `run'         from /usr/bin/gem:23

Has anyone experienced this? Any ideas exactly whats going on or how to correct it?

Thanks! Tim

Is rdoc installed? You should use synaptic/apt-get to install ruby, rdoc, ri and irb. Gems should be installed from source (following instructions at www.rubyonrails.com/down), but it looks like you've got gems installed already. Then re-run 'sudo gem install rails --include-dependencies' and that should work much better. No need to start from scratch. You're almost there. It's just that the Debian/Ubuntu people seem to like breaking packages into many tiny pieces, so just because you have 'ruby' installed doesn't mean you have all the other pieces to have a fully working ruby for installing/running rails.
