These are my experiences of installing Ruby on Ubuntu. I didn’t install the Ubuntu package but went with the source on the Ruby On Rails website. Everything worked fine out of the box, just downloaded the files and followed their instructions (basically the following, in this order.)

Download ruby-1.8.4.tar.gz and rubygems-0.9.0.tgz from the links on http://www.rubyonrails.org/down

Ruby

tar xzf ruby-1.8.4.tar.gz cd ruby-1.8.4 ./configure make make test sudo make install

RubyGems

tar xvf rubygems-0.9.0.tgz cd rubygems sudo ruby setup.rb

Rails

sudo gem install rails --include-dependencies

Test installation

rails railstest/ cd railstest/ ruby script/server Point your browser at http://127.0.0.1:3000
