【问题描述】：

当我尝试 rails g clearance:install 或 rails g sorcery:install 时，它会失败并回复：

/Users/superhappyfuntime/pikipik/config/initializers/devise.rb:3: uninitialized constant Devise (NameError)
    from /Library/Ruby/Gems/1.8/gems/railties-3.1.1/lib/rails/engine.rb:556

    from /Library/Ruby/Gems/1.8/gems/railties-3.1.1/lib/rails/commands.rb:22
    from script/rails:6:in `require'
    from script/rails:6

我怎样才能让它正常工作？

【问题讨论】：

Railties 是 Rails 的一部分。那不是你的问题所在。您应该查看两行：第一行告诉您 Devise 存在问题（您是否按照设置 Devise 的所有说明进行操作？），倒数第五行告诉您错误源于您的应用在config/environment.rb 的第 5 行。第 5 行及其周围的线路是什么？
@Jordan 删除 Devise 解决了这个问题。
如果我想要使用 Devise 并且仍然遇到同样的错误怎么办？我没有安装任何其他身份验证 gem。
@Marc 尝试另一个宝石，如巫术、通关、OAuth、守望者等。

为了解决这个问题，Devise 以某种方式导致了这个问题。
