Installing RoR in Ubuntu 9.10

In a terminal window, install the necessary packages:

sudo apt-get install ruby build-essential libopenssl-ruby ruby1.8-dev
sudo apt-get install rubygems libsqlite3-dev

then Rails -

sudo gem install rails
sudo gem install sqlite3-ruby

and put the path in bash...

pico .bashrc

at the end of my .bashrc file

export PATH=/var/lib/gems/1.8/bin:$PATH

then update Gems and check the versions -

sudo gem update --system
gem list --local

The output:
