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.

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.

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

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.
