当我将 Rails 应用程序（使用 restful_authentication）部署到 Heroku 时，出现以下错误：

/usr/local/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:105:in `const_missing': uninitialized constant User::Authentication (NameError)

我怎样才能让它工作？

您是否在 Heroku 上安装了 gem“restful_authentication”？错误消息表明它不存在。

我在这里摸索，特别是因为你没有提出完整的追溯。

但是，可能与 cache_template_extensions 有关。

http://www.mail-archive.com/heroku@googlegroups.com/msg02172.html 谈到它，关于你的问题，http://forums.pragprog.com/forums/66/topics/2484提到这是升级到 2.3.2 时的一个问题。

底线：在您的代码（development.rb 或附近的某处）中找到引用 cache_template_extensions 的那一行，然后将其删除。

祝你好运。

谢谢大家！看起来这是 Heroku 的问题。我联系了他们的支持，他们不得不做点什么。

现在可以了。:)
