I'm using the below version of ruby and compass:

How to install compass-normalize in ubuntu?

According to compass-normalize git hub

Installation

It is highly encouraged to install from the RubyGems build which
can be found here.

From the command line:

$ gem install compass-normalize

You can also install the gem from your local clone:

$ git clone git://github.com/ksmandersen/compass-normalize.git
$ rake build
$ rake install

Usage

When creating a new project with compass:

$ compass create <my_project> -r compass-normalize --using compass-normalize

If using an existing project, edit your config.rb and add this line:

require 'compass-normalize'

To use the normalize plugin, just import and include normalize:

@import "normalize";

Note: SO Q&A discussion sudo-gem-install-or-gem-install-and-gem-locations

1. 
   

   You can also install gems in your local environment (without sudo) with

   
   
   

   gem install --user-install

   
   



2. I recommend you install RVM and start a happy life with portable gem homes and different version of Ruby all living under one roof.
