My environment:
Mac OS 10.6.4
Ruby 1.8
RubyGems 1.3.7
nokogiri -v:

ruby:
  engine: mri
  version: 1.8.7
  platform: universal-darwin10.0
libxml:
  loaded: 2.7.3
  binding: extension
  compiled: 2.7.3
nokogiri: 1.4.3.1

------the question follows

hi. executing a ruby program using nokogiri and open-uri gives errors
like,

------the error is -------
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/open-uri.rb:32:in
`initialize': No such file or directory - (Errno::ENOENT)
  from

----------------------

the ruby program did work for Ubuntu 8.04 but not for MacOS Snow
Leopard.

Do I need to install something else for MacOS to make the program work?

The error message above looks like it tries to open the empty file name:

16:24:03 $ ruby19 -e 'File.open("")'
-e:1:in `initialize': No such file or directory - (Errno::ENOENT)
        from -e:1:in `open'
        from -e:1:in `<main>'

This means either you passed the empty string in or the code somehow
converted what you passed to this. We would need to see more though
in order to decide what's going on.

Kind regards

robert

Thanks for your reply robert.

As you pointed out, there was a blank line that the ruby program reads.
That was the problem.

Sorry about my carelessness.

Thanks again.

Soichi
