I had downloaded ruby, rails, and rubygems previously on my hard drive when I ran Windows. I just downloaded Ubuntu and tried to use RoR but it wasn't working, so I figured I had to follow the installation procedure listed here http://guides.rubyonrails.org/getting_started.html to get it working. When I type in
sudo gem install rails I get the following error message /usr/local/lib/site_ruby/1.9.1/rubygems/package.rb:383:in `alias_method': undefined method `is_file' for class `Gem::Package::TarReader::Entry' (NameError) from /usr/local/lib/site_ruby/1.9.1/rubygems/package.rb:383:in `<class:Entry>' from /usr/local/lib/site_ruby/1.9.1/rubygems/package.rb:319:in `<class:TarReader>' from /usr/local/lib/site_ruby/1.9.1/rubygems/package.rb:311:in `<module:Package>' from /usr/local/lib/site_ruby/1.9.1/rubygems/package.rb:46:in `<module:Gem>' from /usr/local/lib/site_ruby/1.9.1/rubygems/package.rb:18:in `<top (required)>' from /usr/local/lib/site_ruby/1.9.1/rubygems/custom_require.rb:21:in `require' from /usr/local/lib/site_ruby/1.9.1/rubygems/custom_require.rb:21:in `require' from /usr/local/lib/site_ruby/1.9.1/rubygems/builder.rb:1:in `<top (required)>' from /usr/local/lib/site_ruby/1.9.1/rubygems/custom_require.rb:21:in `require' from /usr/local/lib/site_ruby/1.9.1/rubygems/custom_require.rb:21:in `require' from /usr/local/lib/site_ruby/1.9.1/rubygems.rb:61:in `manage_gems' from /usr/bin/gem:4:in `<main>' I have no idea how to solve this. At this point I just want to delete everything having to do with rails and ruby and start over again.
