Everyone had this experience? You need to compile and install ruby again from source, but this time with the zlib development package installed (I think it’s called “zlib1g-dev” or something like that; I don’t have an Ubuntu machine handy right now) This is so that Ruby can build its own zlib extension. ---

If not, how did you install it? Was it from some non-standard repository? If so, perhaps their package is broken. ---

Thank’s but After zlib1g libs installation the problem has not solved And I didn’t unistall ruby 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 or irb, this commands works normally… ---

Thanks again Brian I compiled ruby from source in the first time. sudo apt-get install gcc g++ build-essential cd /usr/src sudo wget ftp://ftp.ruby-lang.org/pub/ruby/1.8/ruby-1.8.7-p22.tar.bz2 sudo tar -jxvf ruby-1.8.7-p22.tar.bz2 cd /ruby-1.8.7-p22 sudo ./configure sudo make sudo make install ruby -v ruby 1.8.7 (2008-06-20 patchlevel 22) [i686-linux]) …it’s ok cd /usr/src sudo wget [http://rubyforge.org/frs/download.php/38646/rubygems-1.2.0.tgz](http://rubyforge.org/frs/download.php/38646/rubygems-1.2.0.tgz) sudo tar -zxvf rubygems-1.2.0.tgz cd rubygems-1.2.0 sudo ruby setup.rb Doesn’t work… After I install using sudo apt-get install ruby rdoc ri irb libyaml-ruby libzlib-ruby ri ruby1.8-dev or sudo apt-get remove ruby rdoc ri irb libyaml-ruby libzlib-ruby ri ruby1.8-dev sudo apt-get install ruby rubygems irb ri rdoc ruby1.8-dev build-essential or sudo apt-get autoremove ruby ruby rubygems irb ri rdoc ruby1.8-dev sudo apt-get install -y ruby1.8 ri1.8 rdoc1.8 rake irb1.8 Brian C. wrote: > Bruno M. wrote: > > > Thank’s but After zlib1g libs installation the problem has not solved > > zlib1g-dev > > > And I didn’t unistall ruby > > I imagine you compiled ruby 1.8.7 from source, as it’s not a standard > Hardy package.

Post it here if it doesn’t make sense. Do you definitely have the zlib1g-dev package installed? Hmm, perhaps you also need libssl-dev installed. Try that.
