あるディレクトリだけrails sをした際にエラーが出る。

Question

Mac book Airのローカルにruby2.1.2とRails4.1.8がインストールされています。
productというディレクトリに、今まで作ったRailsアプリケーションがあります。
そこで新しく、railsというディレクトリを作りました。
railsディレクトリに、rails new アプリ名で作成し、
コントローラファイルなどをrails gで作りました。
その後、app/routes.rbを編集しました。
編集した全てのファイルは構文チェック済みです。
rails sとしたところ、次のようなエラーがでました。

=> Booting WEBrick
=> Rails 4.1.8 application starting in development on http://0.0.0.0:3000
=> Run `rails server -h` for more startup options
=> Notice: server is listening on all interfaces (0.0.0.0). Consider using 127.0.0.1 (--binding option)
=> Ctrl-C to shutdown server

※エラー文が1000文字を超えるため後半省略しました。

原因わかりますでしょうか？
ちなみに、productの方は動作しました。

Answer 1

今まで通り、productディレクトリで作業を行う事にしました。
新しく、productディレクトリ配下にアプリを作成し、rails sは無事に動作しました。
なぜ、railsディレクトリ配下に作ったアプリは動作しないのか未だに解決していませんが、この質問は閉じさせて頂きます。

Answer 2

ログを見る限り、racc での処理部分でエラーが出ているようです
(詳しくはわかりませんが、Ruby のプログラムコードを生成する構文パーサのようですね)

たとえば 下記のような構文チェッカなどで、機械的に検査されましたでしょうか

• ruby の構文チェック - Qiita
• rails-erb-lint - GitHub

---

探してみると、ほかにも エディタの拡張機能としての構文チェッカなど、その場でエラーを教えてくれるツールなどが見つかるかもしれません

回答ありがとうございます。
構文は2つ目のリンク先に書いてある通りに、
ruby -cw ファイル名で行いました。
全てOKでした。
