【问题描述】：
这是我的实际错误：No route matches [GET] "/members/sign_out"
由于大多数人会使用“用户”，我认为在标题中使用它会更有帮助。无论如何，我根本无法注销。我可以成功编辑我的会员资料。
我正在使用 devise 1.4.2 和 Rails 3.1.0.rc4。此外，我还生成了两个独立的设计模型——一个称为“成员”，另一个称为“管理员”。通过手动导航到正确的 URL 路径（即 localhost:3000/admins/sign_in/），我能够（同时）注册和登录它们。我按照RailsCast on Devise 在我的 application.html.haml 布局文件中创建了一些链接。我知道它只处理“会员”的登录/注销链接。
如果我点击退出链接，我会收到上述错误。如果我手动导航到任一注销 URL（即 localhost:3000/admins/sign_out/），就会发生这种情况。
谁能告诉我为什么会这样？以下是各种相关文件。当然，我是新手……

我遇到了与 OP 对 /users/sign_out 相同的错误，因为我正在获取它而不是删除它（我也是第一年的开发人员）。通过此答案检查 github 后，我提交了拉取请求以更正它！ github.com/plataformatec/devise/pull/2040 去 S.O. ！！！
