Rails服务器突然崩溃了

我正在开发一个应用程序并且rails servr工作正常，但突然它已经停止了 . 我尝试重新启动我的系统（iOS）并一次又一次启动服务器，我收到此错误 -

就在此之前我跑了 - rails generate devise:views

谢谢你的帮助

更多信息 -

• 我曾经使用过 - rails generate devise：install - 之前它创建了一个注册页面 .

• 现在我记得我使用了命令'rails generate devise views'（中间没有冒号）并且它创建了一些文件，但不知道在哪里 . 这会造成一些冲突吗？

• 这是我的Model中的view.rb文件

class View <ActiveRecord :: Base＃包含默认设计模块 . 其他可用的是：＃：token_authenticatable，：confirmmable，＃：lockable，：timeoutable和：omniauthable devise：database_authenticatable，：registerable，：recoverable，：rememberable，：trackable，：validatable

＃为您的模型设置可访问（或受保护）属性attr_accessible：email，：password，：password_confirmation，：remember_me＃attr_accessible：title，：body end
