I’ve heard people describe frustrations they had in getting Rails 3 setup on Ubuntu 10.04 with Ruby 1.9.2. I’m going to outline the steps I’ve taken to do this. Let’s get started installing RVM.
It should be noted that I created a fresh slice on my Rackspace Cloud account to create this tutorial. And I’m assuming you’ve already setup SSH.

Alright, so lets confirm we don’t have ruby installed

Cool, nada. Let’s grab the basic dependencies

Now we’ll install RVM as per their instructions

RVM: shell scripts which allow management of multiple ruby interpreters and environments.

* For JRuby (if you wish to use it) you will need:
$ aptitude install curl sun-java6-bin sun-java6-jre sun-java6-jdk
* For MRI & ree (if you wish to use it) you will need (depending on what you are installing):
$ aptitude install build-essential bison openssl libreadline5 libreadline-dev curl git-core zlib1g zlib1g-dev libssl-dev vim libsqlite3-0 libsqlite3-dev sqlite3 libreadline-dev libxml2-dev git-core subversion autoconf
* For IronRuby (if you wish to use it) you will need:
$ aptitude install curl mono-2.0-devel

WARNING: you have a 'return' statement in your .bashrc, likely this will cause untold havoc.
This means that if you see '[ -z "$PS1" ] && return' then you must change this line to:
if [[ -n "$PS1" ]] ; then
... original content that was below the && return line ...
fi # <= be sure to close the if.
#EOF .bashrc
Even if you use zsh you should still adjust the .bashrc as above.
If you have any questions about this please visit #rvm on irc.freenode.net.
Installation of RVM to /usr/local/rvm/ is complete.
The last part in there about the .bashrc file is important! Using your editor of choice, open the .bashrc file that resides in your user directory.
You need to replace the line that says
[ -z "$PS1" ] && return
with
if [[ -n "$PS1" ]]; then
Now add this to the last line of the file
if [[ -s $HOME/.rvm/scripts/rvm ]] ; then source $HOME/.rvm/scripts/rvm ; fi fi
And yes there needs to be that last fi as it closes the one we added earlier. Save this file with our changes. Now we can check if RVM is setup correctly.
If this doesn’t work you may have to source your .bashrc file to have it reloaded by the current terminal session
After running `rvm notes` if it gives you installation notes about RVM then you’re good to continue, otherwise double check you edited your .bashrc file correctly.
In the notes output RVM tells you what packages you’re gonna need to install for various flavors of Ruby. Since we’re going with 1.9.2 we want the packages it lists under the MRI & ree section. Let’s install those now.
<-- A really long bit of Output Snipped -->
Now we can look at all the RVM known Ruby packages
# MRI Rubies
(ruby-)1.8.6(-p399)
(ruby-)1.8.6-head
(ruby-)1.8.7(-p302)
(ruby-)1.8.7-head
(ruby-)1.9.1-p243
(ruby-)1.9.1-p376
(ruby-)1.9.1(-p429)
(ruby-)1.9.1-head
(ruby-)1.9.2-preview1
(ruby-)1.9.2-preview3
(ruby-)1.9.2-rc1
(ruby-)1.9.2-rc2
(ruby-)1.9.2(-p0)
(ruby-)1.9.2-head
ruby-head
# JRuby
jruby-1.2.0
jruby-1.3.1
jruby-1.4.0
jruby-1.5.1
jruby(-1.5.2)
jruby-head
<-- Output Snipped -->
Next we install the version we want and set it as the default. You’re gonna see RVM install ruby-1.8.7-p302 first, be patient as it will need to also install rubygems-1.3.7, before it finally gets to that 1.9.2.

thanks, helped a lot!
Thanks A lot
Thanks a lot!!
Thank you very much!
Took me a while to figure this out, but since I was adaerly using with-zlib-dir I needed to specify the openssl option with a comma like this:rvm install 1.9.2 -C with-zlib-dir=$rvm_home/usr, with-openssl-dir=$rvm_home/usr
Thank you!!!!!
Thanks for this! One question though, why does vim need to be installed?
I don’t think you have to, but that’s what RVM suggests to do in the install notes.
Thank you. This helped me get Compass/SASS working on Ubuntu 10.04.
It’s very helpful. Thanks!
Thanks, Nice snips.
Thanks for this walkthough, very easy to follow.
