Windows 7, Ruby 1.9.2. The code is just in an arbitrary folder, so I have to include it with "require './file'" because otherwise Ruby can't find it. The error just says there's no such method in my module, here's a snapshot of irb: [code] irb(main):001:0> require './mytest' => true irb(main):002:0> MyTest => MyTest irb(main):003:0> MyTest.class => Module irb(main):004:0> MyTest.test1 NoMethodError: undefined method `test1' for MyTest:Module from (irb):4 from C:/Ruby192/bin/irb:12:in `<main>' [/code] -- Posted via http://www.ruby-forum.com/.
