Nice writeup! Just did a similar setup this week. People may also find the following to be quite useful:

sudo apt-get install libqt4-dev
sudo apt-get install g++
sudo gem install capybara-webkit

sudo gem install curl
sudo apt-get install libcurl4-gnutls-dev
sudo gem install curb

Thank you! very useful..

Thank you! You just made my day. I so did not feel like setting up a new machine "real quick" and stumbled over your Gist. Very nice from A-Z.

olistik commented Oct 1, 2012

@bol-masterchief I've updated that section adding your contribution :-)

Helpful notes, but a linux system is nothing without a good dose of blinkenlights...

sudo apt-get install gkrellm

intel352 commented Dec 4, 2012

Why install rbenv AND rvm? rbenv specifically states it's incompatible with rvm. source:

olistik commented Dec 7, 2012

@intel352: I've mentioned both because when I've created this document I was using rbenv and later I've switched to rvm.
These instructions are just a reference so that if you're going to install one them, you're covered ;-)

Is there any smooth way to install rubygems on rbenv? It seems rvm has but I prefer to use rbenv.. I'm not sure which one is better between apt-get install rubygems and wget rubygems.tgz on ubuntu(I'm using 12.04)

Sorry for my ignorance. I already have gem command except sudo gem because I installed rbenv without sudo.

Thank you for your instruction.

Thank you for writing this up, I can't tell you how many times I have already used this.

you should add curl to the basic pre-requisites :)

olistik commented Mar 9, 2013

@abimaelmartell It's already present in the RVM section.
BTW I'm going to move it upwards since it's used in the Janus setup :-)

olistik commented Mar 9, 2013

@sharms: I'm glad to hear it, I simply made it for myself but it turned out to be useful for others too :-)

also the latest ruby version is 1.9.3-p392

this is a great writeup. Thanks for posting.

olistik commented Oct 20, 2013

@abimaelmartell I've updated the version numbering :-)
