I'm using CentOS 5.5 and typing rvm notes
it gave specific instruction to install mri 1.8.7 before 1.9.2. i.e. rvm install 1.8.7 rvm use 1.8.7 rvm install 1.9.2 This worked for me. here's a copy/paste from my rvm notes: ==== Notes for Linux ( CentOS release 5.5 (Final) ) NOTE: 'ruby' represents Matz's Ruby Interpreter (MRI) (1.8.X, 1.9.X) This is the *original* / standard Ruby Language Interpreter 'ree' represents Ruby Enterprise Edition 'rbx' represents Rubinius bash >= 3.2 is required curl is required git is required (>= 1.7 recommended) patch is required (for ree and some ruby-head's). If you wish to install rbx and/or Ruby 1.9 head (MRI) (eg. 1.9.2-head), then you must install and use rvm 1.8.7 first. If you wish to have the 'pretty colors' again, set 'export rvm_pretty_print_flag=1' in ~/.rvmrc. dependencies: # For RVM rvm: yum install -y bash curl git # 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 iconv-devel # NOTE: For centos 5.4 final iconv-devel might not be available :( # For JRuby (if you wish to use it) you will need: jruby: yum install -y java -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
