Trouble with YAML::load

Ruby
1

I am still working through Beginning Ruby - From Novice to Professional
and
I’ve run into a snag with this code:

Code that should save YAML data as the local variable yaml_string and

then
convert it into an array of Person objects
require ‘yaml’

class Person
attr_accessor :name, :age
end

yaml_string = <<END_OF_DATA

  • !ruby/object:Person
    age: 45
    name: Fred Bloggs
  • !ruby/object:Person
    age: 23
    name: Laura Smith
    END_OF_DATA

test_data = YAML::load(yaml_string)
puts test_data[0].name
puts test_data[1].name

#End of code

Instead it raises this ArgumentError:

ruby grab.rb :

/usr/local/lib/ruby/1.8/yaml.rb:133:in load': syntax error on line 2, col 3:age: 45’ (ArgumentError)
from /usr/local/lib/ruby/1.8/yaml.rb:133:in `load’
from grab.rb:17

Is there something wrong with the code example? Other functions using
YAML
seem to work fine. Is this the sort of thing that I should mention on a
YAML
mailing list?
