execption notifier gem issue

Question

I installed exception_notifier gem following this http://railscasts.com/episodes/104-exception-notifications-revised. But when running rails s, I got this

/home/ruby-2.0.0-p195/gems/actionpack-3.2.13/lib/action_dispatch/middleware/stack.rb:43:in `build': undefined method `new' for ExceptionNotifier:Module (NoMethodError) 

So I tried to Google this problem, and I found that I could use in my production.rb file this config.middleware.use ExceptionNotifier::Rack... insted of this config.middleware.use ExceptionNotifier...

But then I got this message:

uninitialized constant ExceptionNotifier::Rack (NameError)

How should I handle this gem installation ?

Answer 1

If you follow the link https://github.com/smartinez87/exception_notification indicated by @pdobb, you 'll find you have to use

ExceptionNotification::Rack

instead of

ExceptionNotifier::Rack

Answer 2

It's ExceptionNotification::Rack. ExceptionNotifier was for the pre-4.0 versions. See the Getting Started info here: https://github.com/smartinez87/exception_notification for the specifics.
