这是什么路由错误和 rake 路由错误？

Question

我是 Ruby on Rails 的新手。 在摆弄了一个星期后，我决定先给它，买了一本书。全部重新安装。现在，当我认为我已修复它时，我收到一条错误消息：

Routing Error

No route matches "/index"

原来如此

rake routes

这导致了下面的错误列表。

Answer 1

尝试安装旧版本的 rake。

gem install rake -v=0.8.7

您在使用 rake 时可能会收到一条警告消息。

警告：对 Rake DSL 方法的全局访问已被弃用。请包括 ... Rake::DSL 到使用 Rake DSL 方法的类和模块中。

您可以在调用应用程序 load_tasks 之前将“include Rake::DSL”添加到 Rakefile。

我找到了一个帖子来解决这个问题。 Global access to Rake DSL methods is deprecated
