Rails 3 Devise 或 Authlogic - 生产环境神秘地看不到 Gem？适用于开发

Question

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。我已经把头撞在墙上太久了，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。

然而，当我进入生产环境时，每当我尝试 rake db:seed 或运行控制台时，我都会收到此消息。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？似乎能够看到其他宝石就好了。

你看到的 gem 是 Github 版本——这是一个推荐的修复方案，但对我来说不起作用。我使用默认版本和强制使用特定版本得到了相同的结果。

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一些问题？除了 Gemfile 之外还能是什么？

开发 - Rails 3.0.4、1.9.2p136 Prod - Rails 3.0.4、1.9.2p0

最后的手段是升级 Ruby，以便它们匹配，但我怀疑这就是问题所在，而且由于某些原因，这将是大量工作，我不会在这里讨论。

Answer 1

任何机会......

1. 您还没有在生产环境中运行捆绑包（不太可能），
2. 您将您的 gemfile 分为几组 - 您会看到类似这样的

Gemfile

group :development do
     gem 'devise'
end

Answer 2

问题原来是这个切片上安装了另一个 Rails 应用程序，并且由于配置错误，rake/rails 在运行时试图调用另一个应用程序的 rake/rails 脚本。

通过在我的应用程序的 /script 目录中强制使用 Rails 脚本，该问题在短期内得到了解决。例如

ruby script/rails console

，而不是

rails console

但是，我没有找到一种方法来轻松强制我自己的耙子副本。
