所以大家好！

我想使用带有红宝石的rails来让我的网站看起来很漂亮并且使用ruby语言很好。我喜欢红宝石，而且总是如此。很好。

所以我的问题是，为什么我必须看到这个错误？

主要的未定义方法`root'：对象

当我访问我的网站并看到错误的错误页面时，我得到了这个。这是长输出：

无法启动Ruby on Rails应用程序 这些是可能的原因： 应用程序代码中可能存在语法错误。请检查此类错误并进行修复。 可能未安装所需的库。请安装此应用程序所需的所有库。 可能未正确配置应用程序。请检查是否所有配置文件都已正确写入，修复任何错误配置，然后重新启动此应用程序。 应用程序所依赖的服务（例如数据库服务器或Ferret搜索引擎服务器）可能尚未启动。请开始这项服务。 有关错误的更多信息可能已写入应用程序的日志文件。请检查它以分析问题。 错误信息： unde的方法`root'for main：Object 例外类： NoMethodError 应用程序根： /家庭/ $ USER / rails_apps /迷 回溯：

任何人都知道为什么会这样吗？

这里的规格是：

gem list --local rails

*本地宝石*

rails（2.3.14）

ruby​​ -v＆amp;＆amp;宝石-v ruby 1.8.7（2011-02-18 patchlevel 334）[x86_64-linux] 23年1月8日

在我的config / environment.rb中，我指定了rails 2.3.14

建议会很好，也很有帮助。坦克全部！附：请原谅我的英语技能 - 他们不好。

此外，我使用的是cPanel，但没有使用cPanel帐户来查看和处理此应用程序。

2 个答案:

答案 0 :(得分：1)

可能应用程序希望您在config / routes.rb中定义根路由（有关详细信息，请打开config / routes.rb）

答案 1 :(得分：0)

希望这有帮助...我基本上有一个全新的安装。我做了一个脚手架电话：

mirv@rorblog:~/workspace/workspace (master) $ rails g scaffold User userID:integer index  name:string email:string password:string lastLogin:datetime

这显然是错误的...但是如何撤消呢？因为我错误地完成了“rake db：migrate”，然后确定我们可以用一个简单的命令将其删除。错了，但幸运的是，在比较我的github后，我注意到我的routes.rb文件的开头有所不同。 

resources :users

ruby​​ scaffold destroy命令在routes.rb文件中留下了一条小线，它整理了整个东西。没有在github上的差异比较，我从来没有注意到。以下是原始错误，以防人们像我一样盲目地搜索...
