rvm install new ruby version
$ ruby -v # Check ruby version
$ rvm install ruby-X.X.X # Install specific ruby version
$ rvm list # List ruby versions
$ rvm use ruby-X.X.X # Choose a version to use
$ rvm use ruby-X.X.X --default # Set a version as defaulthow to check ruby version
// Command line:
$ ruby -v
// Within irb type "RUBY_VERSION"
# => "2.4.1"
// If using RVM:
$ rvm current
# => ruby-2.4.1install ruby
$ sudo apt-get install ruby-fullruby version from script
There is a RUBY_PATCHLEVEL constant as well. So you can get your version string as
p "#{RUBY_VERSION}-p#{RUBY_PATCHLEVEL}"
