main的局部变量或方法`config':Object(NameError)

Question

我正在关注整合Omniauth Twitter + Devise http://sourcey.com/rails-4-omniauth-using-devise-with-twitter-facebook-and-linkedin/的这篇文章,我遇到了一个阻碍我的问题启动我的rails应用程序.

我想问题是在第8行,config/environment.rb但找不到正确的修复.是否有可能将environment.rb包含在'config/environments /'中？

Answer 1

文章指出你应该把一些代码放在:

config/environments/[environment].rb

在哪里[environment].rb表示以下文件之一:

config/environments/development.rb
config/environments/production.rb
config/environments/test.rb

config/application.rb如果您希望在不同的环境中进行相同的设置,也可以将代码放入.

显示的代码行以config.*,它们应该放在Rails.application.configure do块内.

config/environment.rb在一个典型的Rails应用4只是一个require和Rails.application.initialize!,并且不应该需要修改.
