Install SASS at Ubuntu 14.04 LTS

SASS official site already describe how to install SASS at Linux. When i am going to do according to their instruction. I got some error message. when i typed it in my console or command line.
sudo gem install sass
“sudo: gem: command not found”

After this i googled and tried this one sudo apt-get install rubygems
And once again i got another error message “E: Package ‘rubygems’ has no installation candidate”

So far i fixed by typing this one instead of above one “sudo apt-get install rubygems-integration”
And it worked to me. I got it from this 
So far there are three step to install SASS at ubuntu 14.01 LTS

sudo apt-get update
sudo sudo apt-get install rubygems
sudo apt-get install rubygems-integration
sudo gem install sass

After do this cross-check by typing following command in your console or terminal.

sass -v 

It will return this message “Sass 3.4.21 (Selective Steve)”

Enjoy :)
