ruby-on-rails - 如何诊断并修复此“未初始化的常量”错误？ - Thinbug

我有一个正在运行的Redmine 0.8.0网站，我正在尝试升级到1.2.1（最新的稳定版）。我尽可能地遇到了所有listed requirements并跟随他们的upgrade directions，但我在清理之前就陷入了最后一步 - 迁移。基于下面的证据，我猜测我的基础设施的一部分（Ruby，RubyGems，或者我的一个宝石）不是正确的版本，但我无法弄清楚谁有问题。如何确定解决此问题的下一步？

升级方向说明：

如果您已安装任何插件，则还应运行其数据库迁移。 如果您要在此迁移过程中从Redmine 0.8.x升级，则需要先升级插件迁移 ：

rake db:migrate:upgrade_plugin_migrations RAILS_ENV=production

rake db:migrate_plugins RAILS_ENV=production

运行

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

给出以下错误：

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