		Notes on installing Ruby.

		These notes should be followed before trying to install anything else, like [[Octopress]].

		=Linux=

		I wanted to install this on my [[Netbook]] running Ubuntu 12.04. I read that Ruby 1.9 had some serious flaws (just hearsay), so I'm using 2.0, specifically <code>ruby 2.0.0p247</code>. That means YOU CANNOT USE THE rbenv AND ruby-build IN THE APTITUDE REPOSITORIES!

		You need the bleeding edge stuff. Specifically, bleeding-edge two things:
		* rbenv
		* ruby-build

		==rbenv==

		There are a lot of different versions of ruby out there. Various versions have various uses, but this leads to some version confusion. What we'll do is use a program called <nowiki>rbenv</nowiki> (ruby environment - get it?) to manage our ruby installation and its corresponding gems (gems are like ruby packages).

		First, I installed [https://github.com/sstephenson/rbenv.git rbenv from sstephenson] on GitHub:

		<pre>
		git clone https://github.com/sstephenson/rbenv.git ~/.rbenv
		echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
		echo 'eval "$(rbenv init -)"' >> ~/.bashrc
		</pre>

		When you start a new shell, you should be able to type

		<pre>
		type rbenv
		</pre>

		and see:

		<pre>
		rbenv is a function
		rbenv ()
		{
		[...]
		</pre>

		YAAAYYYY!!!

		==ruby-build==

		The ruby-build package will instruct rbenv where to find various versions of ruby and how to build them.

		Next, install ruby-build from sstephenson,

		<pre>
		git clone https://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build
		</pre>

		And now you should be able to use <code>ruby-build</code> to access various Ruby builds, which you can install and manage with <code>rbenv</code>.

		==Installing the Ruby Version You Want==

		Now all that's left is to install Ruby 2.0 using <code>rbenv</code>:

		<pre>
		rbenv install 2.0.0-p247
		</pre>

		This will take a while. If it looks unresponsive, just pop open another tab and run "top". You'll see either the C compiler or a ruby process cranking away on the CPU until its done.

		Once you've installed your version, you gotta pick which version is going to be your main ruby version.

		First, see if there's already a ruby (maybe a system ruby? old crusty ruby? who knows):

		<pre>
		which ruby
		ruby --version
		</pre>

		Who cares about that. Let's use our own damn <code>rbenv</code> Ruby!!!

		Wait, what Ruby versions do we have?

		<pre>
		rbenv versions
		</pre>

		Oh, yeah, of course. Let's use Ruby <code>2.0.0-p247</code>, which should have been listed in the output of the command above:

		<pre>
		rbenv local 2.0.0-p247
		</pre>

		Now we have our correct version of Ruby (2.0.0-p247) set. Voila!


		=Mac OS X=

		Either follow the above instructions to install rbenv and ruby-build on mac, or just use Homebrew:

		<pre>
		brew update
		brew install rbenv
		brew install ruby-build
		</pre>

== Configuration ==

This one's really easy:

<syntaxhighlight lang="bash">
#!/bin/sh

./configure --prefix=/path/to/ruby
</syntaxhighlight>

You'll probably want to use Ruby gems - these are basically Ruby packages or extensions. You can either use the Gem binary that comes with your Ruby, or alternatively you can install the most up-to-date version yourself by downloading it and installing it. To do that, download and unpack it, then do:

<syntaxhighlight lang="bash">
$ cd /path/to/rubygems
$ ruby setup.rb --help
$ ruby setup.rb
</syntaxhighlight>
