Devise引发了Rails 4.2升级错误 [英] Devise raises error with Rails 4.2 upgrade

问题描述

当我运行 rails s ：

/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 ：

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

推荐答案

似乎这个PR <一段时间前，href =https://github.com/plataformatec/devise/pull/3153 =noreferrer> https://github.com/plataformatec/devise/pull/3153 。更新应用程序中的devise 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 中的设计版本更改为至少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

---

更新：Devise已更新到版本 3.5.x 之前， 4.0 将被发布很快（参见 RubyGems.org 上的所有版本）。这表示您可能想在 Gemfile 中定义至少一个 3.5.x 版本：

---

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 3.5.x version 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'

按照软件包更新设计
