Question

我在线关注youtube教程，当我尝试运行服务器时出现以下错误

=> Booting WEBrick
=> Rails 4.2.6 application starting in development on http://localhost:3000
=> Run `rails server -h` for more startup options
=> Ctrl-C to shutdown server
Exiting
C:/Ruby21/lib/ruby/gems/2.1.0/gems/actionpack-4.2.6/lib/action_dispatch/routing/
mapper.rb:1565:in `root': wrong number of arguments (0 for 1..2) (ArgumentError)

我尝试了捆绑安装和捆绑更新，但我遇到了同样的问题。我尝试删除默认情况下没有的宝石，如波本威士忌，整洁和规范化。仍然是同一个问题。这是我的gemfile的副本。

我怀疑您root中的routes.rb不正确。

它应该是这样的：

root 'posts#index'
