• How do I rescue from a `require': no such file to load in ruby?

  - by René Nyffenegger

  I am trying to rescue from a `require': no such file to load in ruby in order to hint the user at specifying the -I flag in case he has forgotten to do so. Basically the code looks like: begin require 'someFile.rb' rescue puts "someFile.rb was not found, have you" puts "forgotten to specify the -I flag?" exit end I have expected the rescue part to take over execution in case someFile.rb was not found, but my assumption was wrong.
