设计在 Rails 4.2 升级中引发错误 [英] Devise raises error with Rails 4.2 upgrade

问题描述

当我运行 rails s 时:

/Users/galli01anthony/.rvm/gems/ruby-2.1.3/gems/devise-3.2.4/lib/devise/rails/routes.rb:455:in
`ensure in with_devise_exclusive_scope': undefined method `merge!' for
#<ActionDispatch::Routing::Mapper::Scope:0x007f8743e19020> (NoMethodError)

当我运行 rake db:reset 或 db:migrate 或 db:setup 时:

When I run rake db:reset or db:migrate or db:setup:

rake aborted!
NoMethodError: undefined method `merge!' for #<ActionDispatch::Routing::Mapper::Scope:0x007fca8d3f2780>

推荐答案

这个问题似乎已经通过这个 PR 解决了 https://github.com/plataformatec/devise/pull/3153 不久前.更新应用程序中的设计 gem(如果可能).

It seems like the issue was fixed with this PR https://github.com/plataformatec/devise/pull/3153 a while ago. Update the devise gem in your application (if possible).

将 Gemfile 中的 devise 版本更改为至少 3.4.0:

Change the version of devise in your Gemfile to at least 3.4.0:

gem 'devise', '~> 3.4.0'   # or later

然后运行:

bundle update devise

<小时>

更新:Devise 不久前更新到 3.5.x 版本，4.0 将很快发布(查看 RubyGems.org).也就是说，您可能希望在 Gemfile 中至少定义一个版本 3.5.x:

---

Update: Devise was updated to version 3.5.x a while ago and 4.0 will be released soon (see all version on RubyGems.org). That said you may want to define at least a version 3.5.x in your Gemfile:

gem 'devise', '~> 3.5.0'

或者只是加载可能的最新版本:

Or just load the newest version that is possible:

gem 'devise', '> 3.4'

跟随捆绑更新设计
