Question

我执行了捆绑更新，将导轨版本从3.2.13更改为3.2.17，更新了其他一些宝石，并将设计版本从1.5.0更改为3.2.3 }

我修复了一些Devise过时的方法和不兼容性，并遇到以下错误：uninitialized constant Users (NameError)

源自devise_for :users

中的config/routes.rb路由助手

[deprecated] I18n.enforce_available_locales will default to true in the future. If you really want to skip validation of your locale you can set I18n.enforce_available_locales = false to avoid this message.

如何解决？

更新1

我修复了rails并将版本分别设计为3.2.13和1.5.0，然后捆绑更新（更新了许多gems）并仍然得到相同的错误。我想devise和active_support宝石都是无辜的。

正如我在Gemfile.lock中看到的，active_support依赖于两个完全独立的gem：

activesupport (3.2.13)
  i18n (= 0.6.1)
  multi_json (~> 1.0)

虽然Devise取决于以下宝石：

devise (1.5.0)
  bcrypt-ruby (~> 3.0)
  orm_adapter (~> 0.0.3)
  warden (~> 1.1)
    rack (>= 1.0)

无法想象他们中的哪一个出了什么问题

Answer 1

我开始逐个修复宝石版本，并且在我修复了 checker gem的版本后发现错误消失了。在我修复检查器版本之后bundle show的差异输出：

30c30
<   * checker (0.6.6)
---
>   * checker (0.6.2)

所以我最终从我的Gemfile中删除了检查器。

不幸的是，我没有时间调查检查程序影响设计或active_support gems功能的方式。也许以后。

我想问题是在CoreExt.constantize方法中，它覆盖（？）ActiveSupport :: Inflector的相同方法

在Devise升级到3.2.3后出错
