ActionController :: Base的未定义方法`page_cache_extension':Class

Question

出于某种原因,当我运行我的应用程序时,我得到了"ActionController :: Base:Class"的"未定义的方法`page_cache_extension"错误.

奇怪的是,它似乎只是在我启动机器并启动服务器后的第一次启动时发生的.如果我刷新页面 - 它加载正常.如果我重新启动我的服务器 - 它也可以正常工作.

我在windows7上使用rails 3.0.9和ruby 1.9.2并且我认为它在我升级到3.0.7后开始发生.至少,3.0.3我没有得到这个.

这是跟踪:

Answer 1

我从development.rb中删除了以下行

config.action_view.debug_rjs             = true
config.action_controller.perform_caching = false

不确定这是否正确,但它对我有用.

Answer 2

升级我的操作系统后,我尝试了同样的问题.如果使用RVM完成安装,则只使用以下命令:

rvm repair all

Answer 3

刚刚遇到了同样的问题，我发现服务器上的数据库中没有数据 - 我的恢复失败了，因为我忘记创建数据库所需的登录角色。一旦我从备份中正确恢复了数据库，rails 就完美地工作了。

我不确定你是否遇到类似的情况，但我想我会让你知道我是如何解决这个问题的，以防万一你和我处于同一条船上:)祝你好运！
