    thank you. I needed this to get some ruby-based tools installed on centos, and didn’t know enough about ruby to get gem installed and working.

    Hi, I am new to CentOS (6.0.) and followed your blog post to the dot. Unfortunately it rendered my installation somehow useless. All PATHs are gone and the ruby installation fails because of a missing “tput”.. The system was a mess after bash < <(curl -s https://rvm.beginrescueend.com/install/rvm)

    I then logged in and out, restarted and so on.. Nothing really helps. Any help would be appreciated.

    there are additional installs required, which I orignally overlooked, which have to be
    run, embedded in SYSTEM NOTES when step 4 is executed.

    SYSTEM NOTES:

    If you do not wish to enable reading of per-project .rvmrc files, simply set:
    export rvm_project_rvmrc=0
    within either your /etc/rvmrc or $HOME/.rvmrc file, then log out and back in.

    In case your shell exits on entering directory with freshly checked out sources
    you should update .rvmrc file, and replace any `exit ` with `return `.

    You _must_ read ‘rvm requirements’ for additional OS specific requirements for
    various rubies, and native-extension gems. Expect failures until those are met!

    For screen users, please do not forget to read https://rvm.beginrescueend.com/workflow/screen/.
    You will need to add ‘shell -/bin/bash’ to your $HOME/.screenrc to properly load RVM.

    Installation of RVM to /usr/local/rvm/ is complete.

    Requirements for Linux ( CentOS Linux release 6.0 (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 >= 4.1 required
    curl is required
    git is required (>= 1.7 recommended)
    patch is required (for ree and some ruby-head’s).

    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.

    NOTE: To all Multi-User installers – DO NOT forget to add your users to the ‘rvm’ group.
    The installer does not auto-add any users to the rvm group. Admins must do this.
    Group memberships are ONLY evaluated at login time. Log them out, then back in.

    Additional Dependencies:
    # For Ruby / Ruby HEAD (MRI, Rubinius, & REE), install the following:
    ruby:
    !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
    yum install -y gcc-c++ patch readline readline-devel zlib zlib-devel libyaml-devel libffi-devel openssl-devel make bzip2 autoconf automake libtool bison iconv-devel
    !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
    ## NOTE: For centos >= 5.4 iconv-devel is provided by glibc

    # For JRuby, install the following:
    jruby: yum install -y java
    [root@localhost ~]# type rvm | head -l
    head: invalid option — ‘l’
    Try `head –help’ for more information.
    bash: type: rvm: not found
    [root@localhost ~]# type rvm | head -1
    bash: type: rvm: not found
    [root@localhost ~]# type rvm | head
    bash: type: rvm: not found

    [root@localhost ~]# yum install -y gcc-c++ patch readline readline-devel zlib zlib-devel libyaml-devel libffi-devel openssl-devel make bzip2 autoconf automake libtool bison iconv-devel

  • Thank You

    Thank you so much for taking the time to write this up. I am a n00b and I cut and pasted each line and it works perfectly, with the exception of step (7) which I think has an extra period (type) after the 1.9.2.

    is: rvm use 1.9.2. –default

    should be: rvm use 1.9.2 –default

    Anyway, I have my Mac Rails running fine, but things were a mess following Hartl’s setup for Rails 3.1 (not his fault), then I found this, and 10 minutes later I’m finished and ready to code!!

    Great tutorial. Installed RVM on CentOs 6.2 without much issues. Did have to install node.js separately.

    Hey thanks! Everything worked perfectly. There is one update to note when installing rvm. See below:

    bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)
