Commencing RoR (Ruby on Rails) mission–now!

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


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


to install all the necessary components to have a running MVC framework on ruby. I used


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
Once you’ve extracted the tar.gz file,

cd rubygems

to get into the new directory.

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:

As of RubyGems 0.8.0, library stubs are no longer needed.
Searching $LOAD_PATH for stubs to optionally delete (may take a while)...

No library stubs found.

[root@bbs rubygems-0.9.4]#

Then check the gem version

#gem -v

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

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!
