ruby-on-rails - configuration.rb:140:in `const_get' : 未初始化常量 ActionDispatch::Session::EncryptedCookieStore (NameError)

Question

我已经被这个错误困扰了大约 3 天，我不知道如何更正它。任何帮助，将不胜感激。

顺便说一句，我在 Windows 机器上使用 Ruby v.1.9.3p392 & Rails v. 3.2.13

我在出错前发出的命令是:

'rails生成脚手架用户名:string email:string'

错误如下:

好的，所以在从 session_store.rb 文件中删除单词“Encrypted_”之后。它带走了 EncryptedCookieStore (NameError)，现在出现了以下错误，但我不确定它们是否相关:

Answer 1

进入 config/initializers/session_store.rb 并更改:

App::Application.config.session_store :encrypted_cookie_store, key: '_app_session'

到:

App::Application.config.session_store :cookie_store, key: '_app_session'

最近删除了加密的 cookie 存储。希望对您有所帮助。
