Hi all, I've just installed RubyGems 0.9.4 from source (not thru apt-get package) under Ruby 1.8.6 (also source install) and everything went great. But, upon first usage, say installing Rails via: gem install rails --include-dependencies --debug I'll get a whole whackload of Exception 'NameError' from command_manager.rb:145 - uninitialized constant Gem::Commands::BuildCommand (and every other possible command). The file command_manager.rb file (located at: /usr/local/lib/ruby/site_ruby/1.8/rubygems) line 145 is doing this: Gem::Commands.const_get("#{command_name.capitalize}Command").new And that's called once per command that's defined in the commands directory resulting in errors like these: Exception `NameError' at /usr/local/lib/ruby/site_ruby/1.8/rubygems/command_manager.rb:145 - uninitialized constant Gem::Commands::BuildCommand Exception `NameError' at /usr/local/lib/ruby/site_ruby/1.8/rubygems/command_manager.rb:145 - uninitialized constant Gem::Commands::CertCommand Exception `NameError' at /usr/local/lib/ruby/site_ruby/1.8/rubygems/command_manager.rb:145 - uninitialized constant Gem::Commands::CheckCommand Here's my rubygems environment from gems itself RubyGems Environment: - VERSION: 0.9.4 (0.9.4) - INSTALLATION DIRECTORY: /usr/local/lib/ruby/gems/1.8 - GEM PATH: - /usr/local/lib/ruby/gems/1.8 - REMOTE SOURCES: - http://gems.rubyforge.org And here's my PATH environment variable: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/bin/X11:/usr/games I'm running linux under Ubuntu 6.06.1, fresh install, with Ruby 1.8.6 compiled from source and extended with zlib library. Anyone have any ideas of what's going on here? Many thanks, Ben -- Posted via http://www.ruby-forum.com/.
