First I apologize my poor English.

After to install the ruby 1.8.7 patch level 22 from the source
on ubuntu 8.04 hardy succefully.

Then I tryed to install rubygems 1.2 in sequence and I
received this error message:

xyz@xyz: /usr/local/src/rubygems-1.2.0$ sudo ruby setup.rb
/lib/rubygems/spec_fetcher.rb:1:in `require’: no such file to load –
zlib (LoadError)

So I tried install zlib1g and zlib1g-dev and after this the problem has not fixed

And I didn’t unistall ruby for reinstall and recompile…

I tried many kind of commands like for uninstall and re-compile ruby:

sudo apt-get remove ruby libruby libruby1.8 ruby1.8 irb rdoc ri
sudo aptitude remove ruby
sudo dpkg –list | grep ruby, dpkg -r
and through Synaptic too

And when I invoke ruby -v or irb, these commands works normally…

How Can I fix this problem?

Thank’s so much for help me!

Works like a charm. It seems that that gem update –system command can make a problem if you forget to execute as super user.
These are the most useful instructions that work on XUbuntu dapper.

Thank you so much for a very simple easy-to-follow tutorial on setting up Rails on Ubuntu.

I have been so tired of using Windows XP that this weekend I managed to setup a dual boot system with my current Windows XP install and my new favorite operating system Ubuntu.

I used this great tutorial => http://www.linuxdevcenter.com/pub/a/linux/2006/05/08/dual-boot-laptop.html

to get my dual boot system up and running and then I used your tutorial here to get my ROR up and running.

Everything worked according to plan and today I am back coding in Ruby on Rails in my Linux environment.

Thanks a bunch! You saved me tons of time.

For the rest of you…

If you are still using Windows, I suggest you take a look at Ubuntu it is fairly easy to install if you can follow directions.
You won’t be disapointed with this OS and hos much faster and friendlier it is to use.

Ed Arhur -> You need to have universe repositories enabled. Edit your /etc/apt/sources.list to include this line:

deb http://archive.ubuntu.com/ubuntu edgy main restricted universe multiverse

I’ve updated the guide to reflect this.

Right, its the apt-get which fails.

% sudo apt-get install irb
Reading package lists… Done
Building dependency tree
Reading state information… Done
E: Couldn’t find package irb
%

I’m more of a command line kind of guy but I’ve been using the (Syanptic Package Manager) GUI mainly to install packages on this Ubuntu system.

I don’t have the “Community maintained Ope Source software or Software restricted by copyright or legal issues boxes checked.

Thanks,

Ed Arthur -> You can either follow my guide or just run apt-get install irb.
