コントローラアクション用のerbファイルを追加したときに引数が間違っています（0の場合は1）

Question

本当に変な問題に直面していますが、残念ながら、レールはデバッグに有用なスタックトレースを提供しません。私は標準コントローラ、posts_controllerを持っています。ルートでは、私はリソースを定義しました：投稿。

私は基本的なインデックスアクションを実装しました。私が.../postsに行くと、view/postsディレクトリにindex.html.erbファイルが作成されていないため、出力は "Template is missing"です。

このディレクトリに空のindex.html.erbファイルを作成した後、「間違った引数の数（0の場合は1）」が表示されます。

アプリケーショントレースはありません。

フレームワークトレースは次のとおりです。

サーバーのログは、この表示されます。私はこのアプリでは他の多くの複雑なコントローラを持っており、彼らとこの問題に直面していないので、私はかなりそれは非常に馬鹿だと確信しています。 indexアクションのロジックは、index.html.erbファイルなしで動作します（したがって、テンプレートが見つからないというメッセージが表示されます）。しかし、index.html.erbファイルを追加すると、すぐに引数エラーが発生します。私はこれでかなり失われています。

ありがとうございます！
