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.

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