I'm trying to get rails up and running on my development server. It's a fedora14 box. I installed rvm, ruby 1.8.7, and rubygems 1.6.2. When I try to install rails via gem,
gem install rails, i get the following error:
ERROR: Loading command: install (LoadError)
no such file to load -- zlib
ERROR: While executing gem ... (NameError)
uninitialized constant Gem::Commands::InstallCommand
Any ideas as to what is going on. I'm 100% new to ruby/rubygems/rails and I know enough about Linux to be dangerous so any help/suggestions would be greatly appreciated.
Thanks in advance
rvm notes and install whatever it tells you (
zlib-devel will probably be one of the packages you'll need to install via
yum). The output you'll see will be similar to this:
# For Ruby (MRI & Ree) you should install the following OS dependencies: ruby: yum install -y gcc-c++ patch readline readline-devel zlib zlib-devel libyaml-devel libffi-devel openssl-devel ; yum install -y make bzip2 ; yum install -y iconv-devel # NOTE: For centos 5.4 final iconv-devel might not be available :(
You need to install the zlib libraries. A gem is trying to use it with a C extension but it is not found. http://fr.rpmfind.net/linux/rpm2html/search.php?query=zlib-devel&system=&arch= Install zlib-devel.
What this error means is that zlib library is missing. This is a common problem and if you google for it, you'd find loads of information on the same. In ubuntu (where I work) installing the package zlib1g-dev and zlib1g fixes it. I am not sure what the equivalent package in Fedora is, but you should be able to search / find that.
