Subject: Re: Strange Error with parseexcel and classifier...


To recreate the error, you can run test_parser.rb that is part of the
parseexcel test suite.  You need to first install the classifier gem.
Just add require 'classifier' to the test before running it and you
will get the same errors as shown:

  1) Error:
test_str_wk7(TestParser):
NoMethodError: undefined method `downto' for 1/2:Rational

C:/Ruby/lib/ruby/gems/1.8/gems/parseexcel-0.5.1.1/lib/parseexcel/parser.rb:862:in
`str_wk'
    test_parser.rb:521:in `test_str_wk7'

  2) Error:
test_file_bar(TestParser2):

    test_parser.rb:588:in `test_file_bar'

and so on...
