我想问题是在config / environment.rb的第8行,但找不到正确的修复.是否有可能将environment.rb包含在’config / environments /’中？
解决方法
文章指出你应该把一些代码放在：
config/environments/[environment].rb
其中[environment] .rb用于表示以下文件之一：
config/environments/development.rb config/environments/production.rb config/environments/test.rb
如果您希望在不同的环境中进行相同的设置,也可以将代码放在config / application.rb中.
显示的代码行以config.*开头,它们应放在Rails.application.configure do块中.
典型的Rails 4应用程序中的config / environment.rb只是一个require和Rails.application.initialize！,不需要修改.
