string - str.each in Ruby isn't working

Question

I'm Learning Ruby.

I found the method String#each at http://ruby-doc.org/core/classes/String.html.

When I try using it...

irb(main):001:0> "hello
world".each {|s| p s}
NoMethodError: undefined method `each' for "hello
world":String

...but I get that NoMethodError.

I'm using Ruby 1.9.1p253 so I don't think I'm using an old version. What's going on?

Ruby 1.9 no longer has each on the String class. Use either each_char or each_line depending on what you want to do. The docs for Ruby 1.9 String are http://ruby-doc.org/core-1.9.3/String.html.
