Ruby on rails 可配置.rb:30:in`method#u missing'；：未定义的方法`开发'；适用于rails应用程序

我是在OSX机器上运行Ruby 1.9.2的rails新手，当我转向使用Thin时，我遇到了以下错误（值得一提的是，我在一个全新的rails应用程序上使用了gemset，它可以工作，因此我知道这与我编写的代码或配置有关

就我安装的gems而言：

gem 'rails', '3.2.3'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
gem 'thin'
gem 'pg'
gem 'tire'
gem 'newrelic_rpm'
gem 'devise'

这是我在运行“rails c”时遇到的错误

请帮助我…这让我发疯了…或者告诉我自己如何调试这个问题

可能是开发中的错误。rb，第9行是否可能您使用了类似“如果开发就做些什么”的东西，而没有“开发”的问号谢谢Frederick！我扫描了所有的环境文件，发现一个字符不合适。可能是development.rb，第9行出现了错误。您是否可能使用了类似“如果开发就做些什么”的内容，而没有“开发”的问号谢谢弗雷德里克！我扫描了所有的环境文件，发现有一个字符不合适。
