Ubuntu 'Lucid' 10.04 LTS Housekeeping
sudo apt-get update to fetch the latest sources followed by
sudo apt-get upgrade thereby upgrading your install of Ubuntu.
Next, let's install Git, a distributed version control system (DVCS),
curl, as well as the
build-essential package — these are prerequisites for installing RVM, amongst others. Proceed with the following command
$ sudo apt-get install build-essential git-core curl
Let's perform a system wide install of RVM
$ curl -L get.rvm.io | sudo bash -s stable
You should be left with the following details and instructions post-install.
Installing RVM to /usr/local/rvm/ Creating RVM system user group 'rvm' # RVM: Shell scripts enabling management of multiple ruby environments. # RTFM: https://rvm.io/ # HELP: http://webchat.freenode.net/?channels=rvm (#rvm on irc.freenode.net) # Cheatsheet: http://cheat.errtheblog.com/s/rvm/ # Screencast: http://screencasts.org/episodes/how-to-use-rvm # In case of any issues read output of 'rvm requirements' and/or 'rvm notes' Installation of RVM in /usr/local/rvm/ is almost complete: * First you need to add all users that will be using rvm to 'rvm' group, and logout - login again, anyone using rvm will be operating with `umask g+w`. * To start using RVM you need to run `source /etc/profile.d/rvm.sh` in all your open shell windows, in rare cases you need to reopen all shell windows. # mike, # # Thank you for using RVM! # I sincerely hope that RVM helps to make your life easier and more enjoyable!!! # # ~Wayne rvm 1.12.3 (stable) by Wayne E. Seguin <email@example.com>, Michal Papis <firstname.lastname@example.org om> [https://rvm.io/]
As per the above let's add the current user to the
$ usermod -a -G rvm mike
Ensure you logout and back in to your account for changes to take effect. This will always automatically perform
source /etc/profile.d/rvm.sh thereby loading
rvm into your current session.
We need to add the following line to
.bashrc to ensure RVM will be setup in our bash session during future logins
$ echo '[[ -s "/usr/local/rvm/scripts/rvm" ]] && source "/usr/local/rvm/scripts/rvm"' >> ~/.bashrc
You can either logout and back, or for convenience sake simply reload the file via
source .bashrc, thereby ensuring the above changes take effect.
Before we set about installing Ruby, let's install some packages to ensure our Ruby lives are as pain free as possible — you can get the following list by performing
$ sudo apt-get install build-essential openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-0 libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion
You are also urged to look at
rvm notes as well for OS specific notes. Great! We are now ready to install Ruby via RVM.
Proceed to install Ruby 1.9.3, or any other version as you require, via
rvm install 1.9.3. Notice that I have not specified a particular patch-level and therefore RVM will fetch the latest patch level for ruby 1.9.3.
Let's confirm the install went well
$ rvm list rvm rubies ruby-1.9.3-p125 [ x86_64 ] # Default ruby not set. Try 'rvm alias create default <ruby>'. # => - current # =* - current && default # * - default
As seen above,
ruby-1.9.3-p125 has been compiled as is available for use via
rvm. Let's make this our default version of Ruby
$ rvm use 1.9.3 --default && rvm list Using /usr/local/rvm/gems/ruby-1.9.3-p125 rvm rubies =* ruby-1.9.3-p125 [ x86_64 ] # => - current # =* - current && default # * - default
ruby -v also confirms this with its response of
ruby 1.9.3p125 (2012-02-16 revision 34643) [x86_64-darwin11.3.0]
Fantastic! We've configured and successfully setup
ruby-1.9.3-p125 as the default Ruby via RVM.
