At last I found some time to write about my current endeavor: learning and setting up a working web application using Ruby on Rails or more commonly know as RoR or rails.
I’m using Ubuntu Feisty Fawn as of this writing
$ cat /etc/issue Ubuntu 7.04 n l
I haven’t upgraded yet to the latest realease (Gutsy Gibbon ver. 7.10) since I’m waiting for the stability of almost the whole thing to settle down. I’ll probably have a
dist-upgrade
sometime in December, before the holiday break, and before I take a break from development (for a while).
Anyway, this post will be mostly about installation of ruby and of RoR in Ubuntu Feisty Fawn, since I’m just going through ruby and RoR themselves as I write this.
At first I used
synaptic
to install all the necessary components to have a running MVC framework on ruby. I used
synaptic
to install
ruby, gem and rails
. All got into my machine fine.
Apparently, when I got into the code samples using mysql, I ran into code samples which should be very easy but were having errors (inside the ruby console). I’ll probably detail the error and the code some other time when I have more time for weblogging.
But the whole point of this specific post is to swerve you to the (in my opinion) better way of installing rails on Ubuntu (and I think generally on any Linux distribution).
So here it is:
Once you’ve successfully installed ruby (shouldn’t be a problem. You can go ahead and use synaptic with this one), check the version to check further:
$ ruby -v ruby 1.8.5 (2006-08-25) [i486-linux]
That’s okay and done.
Next, download rubygems from http://rubyforge.org/projects/rubygems.
Once you’ve extracted the tar.gz file,
cd rubygems
to get into the new directory.
Enter
sudo ruby setup.rb
which will automatically setup and install rubygems for you. Rubygems will be used to install rail itself.
The output should look something similar to this one:

Searching $LOAD_PATH for stubs to optionally delete (may take a while)... ...done. No library stubs found. [root@bbs rubygems-0.9.4]#
Then check the gem version
#gem -v 0.9.4
Finally, to easily install rails type
sudo gem install rails --include-dependencies
This will fetch and install rails from the Internet, so be patient depending on your Internet download speeds.
The output should be similar to the one below:
# gem install rails --include-dependencies Successfully installed rails-1.2.5 Successfully installed activesupport-1.4.4 Successfully installed activerecord-1.15.5 Successfully installed actionpack-1.13.5 Successfully installed actionmailer-1.3.5 Successfully installed actionwebservice-1.2.5 Installing ri documentation for activesupport-1.4.4...

Installing RDoc documentation for actionpack-1.13.5... Installing RDoc documentation for actionmailer-1.3.5... Installing RDoc documentation for actionwebservice-1.2.5...
And that’s it! You can now start development on the famous RoR framework!
Plus, if you want to update your rails version, all you need to do is type the gem command given above again. It’s that easy!
To further check the installation type
#rails -v Rails 1.2.5
Feedbacks on this installation method plus other ones (or problems with them) are welcome. Feedbacks on RoR are very welcome as well!
