既存のディレクトリでrails sが出来ない

Question

流れ

rails g scaffold board title:string editor:string
を実行
rake db:migrate
を実行
rails s
を実行→起動できない
rails destroy scaffold board
を実行

この作業を間違えて
ホームディレクトリで実行してしまいました

ディレクトリ移動後
rails s
を実行
=> Booting WEBrick
=> Rails 4.0.5 application starting in development on http://0.0.0.0:3000
=> Run rails server -h for more startup options
=> Ctrl-C to shutdown server

このようにrailsが終了してしまい起動出来ません。
新規作成したアプリケーションでは起動できるのですが
既に作成済みのアプリケーションで起動が出来ない状況です。

どうすればいいでしょうか？

誤って作成してしまったRails アプリケーションは、削除することができますか？(作成されるディレクトリやファイルの一覧は、`rails new` を任意のディレクトリで実行すれば、確認することができます)

Answer 1

routes.rbの6行目にエラーがあるようです。
undefined method toとあるので、

root to: 'home#index'

のtoの後ろの:を忘れたとかそんな感じだと思うのですが

ありがとうございました。
root to :'home#index'になっていました。
