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!

You need to create a symbolic link for the gem command.. try this

~$ sudo ln -s /usr/bin/gem1.8 /usr/bin/gem

[...] I’ll install the ruby package, build gems from source, and install rails from gems. Hey! A perfect example of this approach. I’ll repeat the commands I used here, but see that resource for more [...]
