configuration.rb：140：在`const_get'：未初始化的常量ActionDispatch :: Session :: EncryptedCookieStore（NameError）

Question

我一直被困在這個錯誤大約3天了，我無法弄清楚如何糾正它。任何幫助，將不勝感激。

我在Windows機器上的方式，我使用Ruby v.1.9.3p392 & Rails的v 3.2.13

我發出的錯誤是以前的命令：

'軌生成腳手架用戶名：字符串email：字符串'

這是下面的錯誤：

這裏是我的Gemfile：

gem 'rails', '3.2.13'

    gem 'sqlite3', '1.3.7'

好了，從移除單詞 'Encrypted_' 後session_store.rb文件。它帶走了EncryptedCookieStore（NameError）和下面的下面的錯誤現在已經上來了，但我不確定他們是否是相關的：

Answer 1

進入config/initializers/session_store.rb和變化：

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

到：

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

最近刪除了編碼的cookie存儲。希望能幫助到你。
