Question

I successfully installed gem clockwork

C:\web>gem install clockwork
Successfully installed clockwork-0.2.3
1 gem installed
Installing ri documentation for clockwork-0.2.3...
Installing RDoc documentation for clockwork-0.2.3...

but when running simple script

require 'rubygems'
require 'clockwork'
include Clockwork

every(1.minute, 'custom.event.handler' ) do
  puts "This event has its own handler - #{Time.new.strftime("%Y%m%d%H%M%S")}"
end

I get this error

C:\web>ruby clockwork.rb
./clockwork.rb:3: uninitialized constant Clockwork (NameError)
        from C:/Ruby187/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in

        from C:/Ruby187/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in
`require'
        from clockwork.rb:2

Answer 1

Let me give you a hint. The name of your own program is clockwork.rb, and in it you do:

require 'clockwork'

See the problem?
