如何診斷並修復此「未初始化的常量」錯誤？

Question

我有一個工作Redmine 0.8.0網站，我試圖升級到1.2.1（最近的穩定）。我已經遇到了所有的listed requirements，並且儘可能地遵循了他們的upgrade directions，但是在清理 - 遷移之前，我陷入了最後一步。根據以下證據，我猜測我的基礎設施（Ruby，RubyGems或我的寶石之一）的一部分並不是正確的版本，但我無法弄清楚誰是錯。我如何確定下一步解決此問題？

升級的方向狀態：

If you have installed any plugins, you should also run their database migrations. If you are upgrading from Redmine 0.8.x as part of this migration, you need to upgrade the plugin migrations first:

rake db:migrate:upgrade_plugin_migrations RAILS_ENV=production

rake db:migrate_plugins RAILS_ENV=production

運行

$sudo rake --trace db:migrate:upgrade_plugin_migrations RAILS_ENV=production 

提供了以下錯誤：

(in /var/www/html/redmine-1.2.1) 
** Invoke db:migrate:upgrade_plugin_migrations (first_time) 
** Invoke environment (first_time) 
** Execute environment 
rake aborted!

您使用的寶石與您的Rails版本不兼容，可能是因爲寶石已過時。四處尋找更新的版本或自行修補它。
