Ruby

i am using active record in my program and cannot understand what this
error means.

require ‘watir’

include Watir
require ‘active_record’

ActiveRecord::Base.establish_connection(
:adapter => “mysql”,
:host => “127.0.0.1”,
#:host => “sun”,
:database => “Trader”,
:username => “root”,
:password => “password”
)
class Rawdata < ActiveRecord::Base
set_table_name “rawdatas”

It is telling you that firewater and watir required activesupport
2.3.9, so if you want ActiveSupport 3.0.1 you need to require it first
(before requiring watir)

In that case Watir will raise an exception because it strictly loads
2.3.9. There is plan to remove active-support dependency completely in
FireWatir
