odd number list for Hash (SyntaxError), though I am using Ruby 1.8.7 hash declaration - ruby

Question

I am trying to connect to Oracle database using 'activerecord' and Ruby 1.8.7 and getting below error on my Windows 7 machine. I searched around for this issue and came across 1.8 and 1.9 ruby declaration of 'Hash' however I am using Ruby 1.8.7 and I feel I am using correct hash declaration, please correct me if I am wrong.

This is how my code looks like

gem "activerecord-oracle_enhanced-adapter"
require 'active_record'
ActiveRecord::Base.establish_connection(
:adapter => "oracle_enhanced",
:database => "someurl.net:1523/ABCAD",
:username => "testing1",
:password => "testing1")
class TestTable < ActiveRecord::Base
set_table_name "TABLE_NAME"
set_primary_key "ID"
end
TestTable.find(:all).each do |tt|
p tt
end
nac = TestTable.new()
Additional Information:
I have below gems on my machine :
* LOCAL GEMS *
actionmailer (2.3.4)
actionpack (2.3.4)
activerecord (2.3.4)
activerecord-oracle_enhanced-adapter (1.5.3)
activeresource (2.3.4)
activesupport (2.3.4)
json (1.8.1)
mysql (2.9.1 x86-mingw32)
rack (1.0.1)
rails (2.3.4)
rake (10.1.1)
ruby-oci8 (2.1.7 x86-mingw32)
rubygems-update (1.4.2)
I use below Rubygems version:
C:\Users\tester1>gem -v
1.4.2
I tried to connect using OCI8 and I was able to get response out of Oracle database so there is no connectivity issue from my machine.
irb(main):006:0> OCI8.new('testing1', 'testing1', 'someurl.net:1523/ABCAD').exec('select sysdate from dual') do |r| puts r.join(', ') end

Answer 1

The error message shows that your error is coming from inside the activerecord-oracle_enhancedadapter gem, and that gem has a Ruby 1.9 style hash. You might find an older version of that gem that supports Ruby 1.8 and switch to that version.
