uninitialized constant Enumerable::Enumerator

[rahulsom]

I'm trying to look at recurrences of a calendar event and running into that error

Here's my code

  calendars = Vpim::Icalendar.decode(ics)
  calendars.each do |calendar|
    cal_data = calendar.
        select  { |event| event.occurs_in?(Time.now, Time.now + 86400 * 10) }.
        collect { |event| event_hash(event) }.
        sort_by { |event| event['end'] }.
        each    { |event| puts event }
  end

The full trace is here

I'm using ruby 2.1.2 and vpim 13.11.11 if that makes a difference.
