SugarCRM.connect fails.

[prasadsurase]

Hi, I am using sugarcrm(0.9.18) with ruby 2.3.3. The connection fails for the below code stating sugarcrm-0.9.18/lib/sugarcrm/module.rb:23:in initialize': undefined method classify' for #<Hash:0x007fdbcb97fb18> (NoMethodError)

require 'active_support'
require 'sugarcrm'
SugarCRM.connect("someurl", 'somename', 'somepassword')

Am I doing something wrong or missing something?
