Upgrading Ruby Gems

Ruby Gems is used to install, update and remove Ruby libraries from your system.

To update the core Rails components on your server, use the following command:


sudo gem update --system

If this fails, follow these steps to upgrade it manually:


  wget http://rubyforge.org/frs/download.php/45905/rubygems-1.3.1.tgz
  tar xfz rubygems-*
  cd rubygems-*
  sudo ruby setup.rb
  cd ..
