ruby-on-rails - 主要 :Object 的未定义方法 `root'

Question

我的问题是，为什么我必须看到这个错误？

undefined method `root' for main:Object

当我访问我的站点并看到错误的 Phusion 页面时，我得到了这个。这是长输出:

Ruby on Rails application could not be started These are the possible causes: There may be a syntax error in the application's code. Please check for such errors and fix them. A required library may not installed. Please install all libraries that this application requires. The application may not be properly configured. Please check whether all configuration files are written correctly, fix any incorrect configurations, and restart this application. A service that the application relies on (such as the database server or the Ferret search engine server) may not have been started. Please start that service. Further information about the error may have been written to the application's log file. Please check it in order to analyse the problem.

这里的规范是:

gem 列表 --local rails

*** 本地 gem ***

rails (2.3.14)

ruby -v && gem -v ruby 1.8.7 (2011-02-18 补丁级别 334) [x86_64-linux] 1.8.23

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

此外，我正在使用 cPanel，但没有使用 cPanel 帐户查看和处理此应用。

可能应用希望您在 config/routes.rb 中定义根路由(打开 config/routes.rb 了解详细信息)
