rails s ができない (rack関連のエラーが出ます)

Question

railsのサーバを起動しようとするとrack関連のエラーが出ます
色々試してみたんですがエラーが解決しませんでした。
エラーの解決法知ってる方がいらしたらぜひよろしくお願いします。

$ rails s
=> Booting WEBrick
=> Rails 5.1.3 application starting in development on http://localhost:3000
=> Run `rails server -h` for more startup options

Answer 1

エラーメッセージを読む限り、config.ruという、Rack用の設定ファイルに、なぜか間違ってgit config 以下の行が書かれているようです。

config.ruを確認してみてください。
