Ubuntu...?

Use this to find out what executable you're running:

$ which ruby
/usr/bin/ruby

Use this to find out what it actually is:

$ readlink -f /usr/bin/ruby
/usr/bin/ruby1.8

Use this to find out what package it belongs to:

$ dpkg -S /usr/bin/ruby1.8
ruby1.8: /usr/bin/ruby1.8

Use this to uninstall that:

$ apt-get purge ruby1.8

Note: If you have installed Ruby using Version/Environment managers like RVM or Rbenv then this method is not gonna work because Rubies will be installed as scripts not packages.

    Please stop, and go read the instructions at the rvm home page; they are quite extensive and well-written. Ask if you have any *specific* problems. – Amadan Mar 31 '14 at 05:07

If you used rbenv to install it, you can use 

rbenv versions

to see which versions you have installed.

Then, use the uninstall command: 

rbenv uninstall [-f|--force] <version>

for example:

rbenv uninstall 2.4.0  # Uninstall Ruby 2.4.0

If you have installed Ruby using RVM then the following command will completely remove RVM installed directory:

rvm implode

Running this command will ask for your confirmation to delete the .rvm directory.

After it completes deleting the .rvm directory, you get the following message which is worth notable:

Note you may need to manually remove /etc/rvmrc and ~/.rvmrc if they exist still.

Please check all .bashrc .bash_profile .profile and .zshrc for RVM source lines and delete or comment out if this was a Per-User installation.

At first find out where ruby is? then

rm -rf /usr/local/lib/ruby
rm -rf /usr/lib/ruby
rm -f /usr/local/bin/ruby
rm -f /usr/bin/ruby
rm -f /usr/local/bin/irb
rm -f /usr/bin/irb
rm -f /usr/local/bin/gem
rm -f /usr/bin/gem

Or you can try this one also.

aptitude purge ruby

    Impatient, are we? Because removing libraries installed through package system should be removed through the package system. In addition to introducing inconsistency, it also misses quite a bit of files (e.g. the documentation files). At the time of the downvote, you did not have the `aptitude` alternative (and it's downvote-worthy anyway as long as the `rm` bit stands). – Amadan Mar 31 '14 at 05:04
  • Ok but i am doing work and try to update the solution and provide better answer to him, so you should wait for some time to downvote. And also i know that downvote is useful for user to check the good answer and bed answer as well. – Bharat soni Mar 31 '14 at 05:08
