最近、アプリケーションを Rails バージョン 2.1.2 からバージョン 2.2.2 にアップグレードしました。開発と私のステージングシステムでテストされました。本番環境に移行したとき、environment.rb ファイル全体をロードできませんでした。（なぜ、ああ、なぜ、それは常に生産されているのですか!?!）

以下は私のenvironment.rbファイルです

# Be sure to restart your web server when you modify this file.

# Uncomment below to force Rails into production mode when 
# you don't control web/app server and can't set it the proper way

  # config.plugins = %W( exception_notification ssl_requirement )

  # Add additional load paths for your own custom dirs
  # config.load_paths += %W( #{RAILS_ROOT}/extras )

  # Force all environments to use the same logger level 
  # (by default production uses :info, the others :debug)
  # config.log_level = :debug

  # Use the database for sessions instead of the file system
  # (create the session table with 'rake db:sessions:create')

Rails gem をバージョン 2.1.2 に使用するように設定すると、すべてが読み込まれ、すべてのputsステートメントが期待どおりに出力されます。gem のバージョンを 2.2.2 に変更すると、表示される最後のステートメントは " setting smtp settings" です。

セクションを一番下に移動するRails::Initializer do |config|と、現在の場所よりも悪い方法で失敗します。

システムにロードされている ruby​​ のバージョンは、Ruby 1.8.6 パッチレベル 111 です。RHEL5-64bit で実行されています。

私は困惑しています。アイデア？提案？

rake rails：updateを実行しましたか？

また、ほとんどのコードをconfig / initializers / [anything] .rbに移動することもできますが、それ自体で問題が解決するとは思えません。
