Kehoe のLearn Ruby on Railsの 147 ページ (epub) にいて、このコードをconfig/environments/development.rbにコピーしました。

config.assets.debug = true
   config.action_mailer.smtp_settings = {
    address: "smtp.gmail.com",
    port: 587,
    domain: Rails.application.secrets.domain_name,
    authentication: "plain",
    enable_starttls_auto: true,
    user_name: Rails.application.secrets.email_provider_username,
    password: Rails.application.secrets.email_provider_password
  }

ただし、その後、サーバーを実行しようとすると、次のようになります。

チュートリアルに従って、Ruby 2.1.2 と Rails 4.1.4 をインストールしました。乗り越えるにはどうしたらいいですか？本の GitHub リポジトリのファイルを使用してみましたが、結果は同じです。プロジェクトは次のとおりです。

スタック トレースは、障害がconfig/environments/development.rbの 32 行目にあることを示しています。

次のように置き換えdomain: Rails.application.secrets.domain_nameてみてください:

domain: "example.com",

引用符とコンマが必要です。

36 行目で引き続きエラーが発生した場合 (報告どおり)、以下を置き換えます。

user_name: "my_user_name",
password: "my_password"

config/secrets.ymlファイルが正しく設定されていないという問題があります。config/secrets.ymlファイルが環境変数を使用してドメイン値を設定する場合、環境変数が正しく設定されていない可能性があります。Unix 環境変数の設定に問題がある場合は、資格情報をconfig/secrets.ymlファイルに直接追加できます。その場合、ファイルからシークレットを削除するまで、ファイルを Git にチェックインしないでください。
