Hi I have installed CentOS 5.2 on my PC. Ruby 1.8.5 and Ruby-devel packages are already installed. I have downloaded rubygems-1.3.1.tgz package and installed it. Now I am trying to install Rails by the command below: gem install rails But it gives me the following error: ERROR: While executing gem ... (Zlib::DataError) incorrect header check zlib and zlib-devel are already installed on my pc. I can install other gems like hpricot etc. But still I cannot install rails. Can somebody please guide me how can I install rails on CentOS? Thank you, Paryank

Hi Paryank, Though I have no direct solution for you, I think compile/install Ruby 1.8.7 may solve this problem, while ruby packages on CentOS is obsolete. Jan * Paryank <firstname.lastname@example.org> [2009-02-09 21:29:44 -0800]:

Thanks for your help. But it still does not work. I have downloaded ruby source, compiled and installed. It still gives the same error! I do not understand what I am missing!

Here is what I have - it may be a little old now - from notes to get our CentOS sever running. INSTALLING RUBY ON RAILS: ========================= 1) Install Ruby See: http://rubyonrails.org/down wget http://ftp.ruby-lang.org/pub/ruby/1.8/ruby-1.8.6.tar.gz tar -zxvf ruby-1.8.6.tar.gz cd ruby-1.8.6 ./configure --with-openssl-dir=/usr/lib/openssl make sudo make install These MAY not be needed. Come back and do them if things don't go right in install ruby gems and rails. 1a) zlib support cd ruby-1.8.6 ruby extconf.rb --with-zlib-include=/usr/include --with-zlib-lib=/usr/ lib make sudo make install 1b) openssl cd ruby-1.8.6/ext/openssl ruby extconf.rb make sudo make install 2) Install ruby gems wget http://rubyforge.org/frs/download.php/28174/rubyge... tar -zxvf rubygems-0.9.5.tgz cd rubygems-0.9.5 sudo ruby setup.rb config sudo ruby setup.rb setup sudo ruby setup.rb install 3) Install Rails: sudo gem install --version '2.1.0' rails --include-dependencies 4) Install Mongrel sudo gem install mongrel mongrel_cluster

Thanks phil, But I still have the same error. I have removed my existing ruby package by: yum remove ruby And then followed the steps you have mentioned. But when I run command to install rails first it try to update rubygems. It was taking very long time. So I have updated rubygems by the following command: gem update --system After gem is successfully updated, I tried again to install rails. But it was giving the same error again: ERROR: While executing gem ... (Zlib::DataError) incorrect header check

Ok, Here is what I have to prep the box - this may not apply as it depends on your install, but maybe you can look through here and see. PREP THE SYSTEM: ================ 0) As root: rpm -i http://ftp.gui.uva.es/sites/centos.org/4.6/os/i386... rpm -i http://ftp.gui.uva.es/sites/centos.org/4.6/os/i386... rpm -i http://ftp.gui.uva.es/sites/centos.org/4.6/os/i386... rpm -i http://ftp.gui.uva.es/sites/centos.org/4.6/os/i386... rpm -i http://ftp.gui.uva.es/sites/centos.org/4.6/os/i386... rpm -i http://ftp.gui.uva.es/sites/centos.org/4.6/os/i386... rpm -i http://ftp.gui.uva.es/sites/centos.org/4.6/os/i386... rpm -Uvh http://ftp.gui.uva.es/sites/centos.org/4.6/os/i386... rpm --import http://mirror.centos.org/centos-4/4.6/os/i386/RPM-... 1) install gcc sudo yum install -y gcc 2) install wget sudo yum install -y wget 3) install various other things that came up! sudo yum install -y fedora-rpmdevtools -- not found/needed sudo yum install -y openssl-devel sudo yum install -y zlib zlib-devel sudo yum install -y libjpeg-devel libpng-devel glib2-devel fontconfig- devel zlib-devel libwmf-devel freetype-devel libtiff-devel sudo yum install -y cabextract -- not found sudo yum install -y pcre-devel sudo yum install -y subversion sudo yum install -y readline-devel 4) Create a file in $HOME called .rpmmacros with the following line in it %_topdir %(echo $HOME)/rpmbuild create the directories $HOME/rpmbuild/BUILD and $HOME/rpmbuild/RPMS/ noarch 5) cabextract wget http://centos.karan.org/el4/extras/stable/i386/RPM... sudo rpm -ihv cabextract-1.1-2.i386.rpm 6) get ssh keys in place http://homepage.mac.com/kelleherk/iblog/C190154847...

I have a pretty good step by step on setting up rails on a GoDaddy CentOS server: <a href="http://blog.sonerdy.com/2009/01/setting-up-rails-o... up Rails on CentOS</a> This uses passenger. Hope it helps!
