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!

My instructions were to install RubyGems via their <b>source, not apt-get</b>. I would suggest either: Remove rubygems (<code>apt-get remove rubygems</code>) and install via my instructions <b>Or:</b> Add <code>/var/lib/gems/1.8/bin</code> to your $PATH environment. Open up your <code>~/.bashrc</code> and add <code>export PATH=$PATH:/var/lib/gems/1.8/bin</code>. Restart your terminal, and it should work. Regards, Aizat Hi Chris, I see your problem.
