undefined method `new' for "Rack::Bug":String>

[jarl-dk]

I have installed the gem

I have added the line
config.middleware.use "Rack::Bug", :secret_key => "adsfl232343sdfs24759uweafsdfsd5234"
to my environments/development.rb

I can start the server, but when I hit my application by pointing my browser to
http://localhost:3000/**rack_bug**/bookmarklet.html
I get the error:
hermes157~/projects/inseeto/pegasus-performance:./script/server

Have you tried giving Rack::Bug as constant instead of string?

[jarl-dk]

No. I just followed the guide: http://github.com/brynary/rack-bug. I'll try it soon.

[jarl-dk]

Now I have tried
config.middleware.use Rack::Bug, :secret_key => "adsfl232343sdfs24759uweafsdfsd5234"
as well, but now it won't even start my server. it says

[josevalim]

Oh, try ::Rack::Bug instead of Rack::Bug.

[jarl-dk]

Done. Same problem, server wont start with ST as above.

[mattetti]

require 'rack/bug'
config.middleware.use ::Rack::Bug, :secret_key => "adsfl232343sdfs24759uweafsdfsd5234"
