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:

这里的规范是:

gem 列表 --local rails

*** 本地 gem ***

rails (2.3.14)

ruby -v && gem -vruby 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)
