这个问题可能很容易解决，但不知何故我找不到解决方案。
Authlogic 和 Devise 都会发生这种情况。我一直在用头撞墙很长时间，以至于我实际上撕掉了 Authlogic 并重新启动了 Devise——但遇到了同样的问题。
在开发上一切都很好。
但是，当我开始生产时，每当我尝试 rake db:seed 或运行控制台时都会得到这个。这也显示我重新启动服务器和我的 gemfile。
为什么生产看不到宝石？它似乎能够看到其他宝石就好了。
您看到的 gem 是 Github 版本——这是推荐的修复程序，对我不起作用。我使用默认版本和强制特定版本得到相同的结果。
Authlogic 和 Devise 都存在相同问题的事实似乎表明我的生产配置存在问题？除了 Gemfile，它还能是什么？
开发 - Rails 3.0.4、1.9.2p136 产品 - Rails 3.0.4、1.9.2p0
最后的手段是升级 Ruby 以使它们匹配，但我怀疑这是问题所在，由于某些原因，我不会在这里进行大量工作。
