Nokogiri installation error for Ruby 1.8.7 for Linux OS

Question

I am working with Rails 3.2.1 and ruby 1.8.7 on Linux OS. I am trying to install Nokogiri for Authorize-net gem on a WHM Server. I am getting the following error :

gem install nokogiri -v '1.5.0'

Building native extensions.  This could take a while...
ERROR:  Error installing nokogiri:

libxslt is missing.  please visit http://nokogiri.org/tutorials/installing_nokogiri.html for help with installing dependencies.

*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

The mkmf.log file states that libxslt is missing.

When trying to install libxslt-ruby, I'm getting the following error :

I am developing on Windows machine but the client's server is Linux. I tried googling but no luck.

Any help would be highly appreciated!

Thanks in advance!

I think "libxslt is missing" doesn't mean you have to install gem libxslt-ruby. It's telling you to install package libxslt-dev.

Just follow http://nokogiri.org/tutorials/installing_nokogiri.html and run:

sudo apt-get install libxslt-dev libxml2-dev
sudo gem install nokogiri
