rails sでエラーが出てしまいました

Question

rails sでサーバーを立ち上げようとした際に以下のようなエラー文が出てしまいました。他のプログラミングの質問サイトで同じ質問をしてみたところ、もう一回環境構築をやってみてと投げやりな返答しか来なかったので、どこが間違っているのか有識者の方は教えて頂きたいです。
windowsでrailsの勉強していて、これまでも環境構築で苦い思いしています。

Did you mean? root

エラーメッセージの一番最後に原因が書かれていますね。config/routes.rbの中身を貼り付けていただけますか？
rootの前になにやら空白スペースが入っているっぽいですが。。

Answer 1

エラーメッセージをみると、

/home/shota/rails_app/config/routes.rb:2:in block in <main>': undefined method `　root' for #

となっていますので、routes.rbが問題かと思われます。
routes.rbの中が間違っていないか確認してください。

ちなみにwindows上でそのままrubyを使うのは茨の道ですので、
cloud9やvagrantなど他の方法を使うことをおすすめします。

などに環境構築の方法が載ってますので、参考にしてください。
