Install Ruby 1.9.2 on Ubuntu

An article by f00    4 Comments

As you all know Ruby is one of the most popular programming language on the web. It is recommended to install ruby 1.9.2 instead of 1.8.x

I tried to install ruby from the package manager on Ubuntu, but ruby 1.9.2 is not there in the repo.

So, I am going to show you how to install ruby 1.9.2 on Ubuntu

Step 1 -

Fire up the terminal and execute these few commands -

 $ sudo apt-get install build-essential zlib1g zlib1g-dev libruby1.9.1 libxml2 libxml2-dev libxslt1-dev
 $ sudo apt-get build-dep ruby1.9.1
 $ wget ftp://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.2-p0.tar.bz2
 $ tar xvjf ruby-1.9.2-p0.tar.bz2

Step 2 -
Open ruby-1.9.2-p0/ext/Setup and uncomment the zlib line.

Step 3 -
Now, simply configure, compile and install it! -

 $ ./configure
 $ make
 $ sudo make install

AND RUBY 1.9.2 IS INSTALLED!

To check the ruby version -

 $ ruby -v
 => ruby 1.9.2p0 (2010-08-18 revision 29036) [x86_64-linux]

To check the rubygems version -

 $ gem -v
 => 1.3.7

Hope this quick tip will help many Ubuntu users who want to install ruby 1.9.2

Cheers!
