How do I rescue from a `require': no such file to load in ruby?
exception, require, ruby
Solution
rescue without arguments rescues only StandardError s. The LoadError (that is raised by a file not found) is not a StandardError but a ScriptError (see http://blog.nicksieger.com/articles/2006/09/06/rubys-exception-hierarchy). Therefore you have to rescue the LoadError explicitly, as MBO indicated.
Problem
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.
