Ruby on rails 获得；无法加载这样的文件--designe（LoadError）"；在终端中使用$rails服务器时

我是rails的新手，在我正在处理的一个项目中，我遇到了

design

方面的问题

在尝试测试应用程序（之前运行良好）并启动

$rails s

时，我得到了以下堆栈跟踪：

Patricks-MacBook-Air:rails-prelaunch-signup patrickvihtelic$ rails s
/Users/patrickvihtelic/code/rails-prelaunch-signup/config/application.rb:13:in `require': cannot load such file -- devise (LoadError)

任何提示或建议将不胜感激-谢谢

您使用的是什么Desive版本？您是否“捆绑安装”Desive？
