How can I update Ruby version 2.0.0 to the latest version in Mac OS X v10.10 (Yosemite)?

I need to update my Ruby version from 2.0.0 to the latest version. I can not use some gems because my version is not updated.
I had used Homebrew to install Ruby some time ago. How can I update my Ruby version?

Open your terminal and run
curl -sSL https://raw.githubusercontent.com/rvm/rvm/master/binscripts/rvm-installer | bash -s stable


For the rvm command to work, you need to run:
source ~/.rvm/scripts/rvm


Now, run rvm list known

This shows the list of versions of the Ruby interpreter.

Now, run rvm install ruby@latest to get the latest Ruby version.

If you type ruby -v in the terminal, you should see ruby X.X.X.

If it still shows you ruby 2.0., run rvm use ruby-X.X.X --default.

Prerequisites for Windows 10:

• C compiler. You can use http://www.mingw.org/

• make command available otherwise it will complain that "bash: make: command not found". You can install it by running mingw-get install msys-make

• Add "C:\MinGW\msys\1.0\bin" and "C:\MinGW\bin" to your path environment variable
