Convert date

Ruby
1

in my irb console:
irb(main):001:0> require ‘rubygems’
=> true
irb(main):002:0> require ‘date’
=> false
irb(main):003:0> puts Date.parse(“oct”).to_s.split("-")[1]
10
=> nil

1.why
irb(main):002:0> require ‘date’
=> false

2.is there more simple way to change “oct” into 10?

This is odd.
Although i’d like to point out that ‘Date’ library is not part of
rubygems
and you don’t need to require ‘rubygems’ before requiring ‘date’.
Perhaps you might want to try and require ‘date’ without requiring
‘rubygems’…

Beyond that I would need more info regarding your setup to comment on
anything, what ruby version, what OS, how did you install ruby, etc…

Something already included it. Possibly something in Rubygems,
possibly something irb loads automatically.

2.is there more simple way to change “oct” into 10?

irb(main):004:0> dates = {“jan” => 1, “feb” => 2, “oct” => 10}
=> {“oct”=>10, “jan”=>1, “feb”=>2}
irb(main):005:0> dates[“oct”]
=> 10

or

months = %w{jan feb mar apr may jun jul aug sep oct nov dec}
num = months.find_index('oct') + 1
