我是Ruby on Rails的新手.
在摆弄了一个星期之后我决定放弃它,买了一本书.全部重新安装.现在,当我以为我修复它时,我收到一个错误说：

Routing Error

No route matches "/index"

所以我做了

rake routes

这导致了下面的错误列表.

解决方法

尝试安装旧版本的rake.

gem install rake -v = 0.8.7

使用rake时可能会收到警告消息.

警告：不建议全局访问Rake DSL方法.请包括
… Rake :: DSL成为使用Rake DSL方法的类和模块.

在调用应用程序load_tasks之前,您可以在Rakefile中添加“include Rake :: DSL”.

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