Basic question: how to use Enumerable#each_slice

This are examples from library documentation
(1…10).each_slice(3) {|a| p a}
(1…10).each_cons(3) {|a| p a}

but when I run them in fxri, got such errors:

undefined method `each_slice’ for 1…10:Range

Do I need to require any module?

Yes, enumerator.
