Question

我作为最后的手段来到这里。我无法在互联网上的任何其他地方找到解决方案。非常感谢您的帮助。我正在rails 4中创建一个应用程序，我正在松散地遵循一个旧教程，可以在https://github.com/schneems/reddit_on_rails

找到

当我尝试运行时

rails generate devise user

我收到此错误消息：

config/application.rb:25:in `<top (required)>': undefined local variable or method    

`config' for main:Object (NameError)

/kernel_require.rb:55:in `require'
from -e:1:in `<main>'

这是我的application.rb文件：

require File.expand_path('../boot', __FILE__)

require 'rails/all'

# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(*Rails.groups)

module Stonedandalone
class Application < Rails::Application
# Settings in config/environments/* take precedence over those specified here.
# Application configuration should go into files in config/initializers
# -- all .rb files in that directory are automatically loaded.

# Set Time.zone default to the specified zone and make Active Recordauto-convert        

to  this zone.
# Run "rake -D time" for a list of tasks for finding time zone names. Default is UTC.
# config.time_zone = 'Central Time (US & Canada)'

# The default locale is :en and all translations from config/locales/*.rb,yml are auto  

loaded.
# config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}').to_s]
# config.i18n.default_locale = :de
  end
end

config.assets.initialize_on_precompile = false


#The last line is the one that caused the error.

只需将config行向上移动几行即可进入班级：class Application < Rails::Application。

未定义的变量或方法＆＃39; config＆＃39; for main：用于Rails 4的application.rb中的对象？
