undefined local variable or method `config' for main:Object - rails

Question

When I run the rails application, I get the following error:

undefined local variable or method "config" for main:Object

How can I resolve it?

Answer 1

My guess is that you found some code examples from an older version of rails, which called for you to place a config.gem * in your environment.rb file. To fix this add the gem requirement to your gemfile.

Answer 2

in your enviroment.rb file, cut any line starting with config and paste into your production.rb/development.rb/test.rb instead.

This is what worked for me when I had a similar problem.
