local variable or method `config' for main:Object (NameError)

Question

I\'m following this post for integrating Omniauth Twitter + Devise http://sourcey.com/rails-4-omniauth-using-devise-with-twitter-facebook-and-linkedin/ and I have encounter an i

Answer 1

I have also faced such an error(

NameError: undefined local variable or method `server' for main:Object
        from (irb):1
        from C:/RailsInstaller/Ruby2.2.0/bin/irb:11:in `
'),

)

maybe its because I am a Newbie in ruby on rails. hence instead of starting the rails server from direct command line I tried it to start from inside of IRB hence I got that error.

when I came out of IRB and started the server again from CMD it started smoothly.
