运行"rails generate devise:install“时，从devise获得错误"User not respond to 'devise‘method”。

Question

在运行"rails generate devise:install“时，我从devise得到了错误"User not respond to 'devise‘method”。想法:你该如何解决？

实际上，当我尝试运行"rails generate devise:install“时，也会遇到这个错误。

备注：

Gregs-MacBook-Pro:testapp greg$ rails generate devise:install
/Library/Ruby/Gems/1.8/gems/devise-2.0.1/lib/devise/rails/routes.rb:406:in `raise_no_devise_method_error!': User does not respond to 'devise' method. This usually means you haven't loaded your ORM file or it's being loaded too late. To fix it, be sure to require 'devise/orm/YOUR_ORM' inside 'config/initializers/devise.rb' or before your application definition in 'config/application.rb' (RuntimeError)

Answer 1

听起来你已经在你的用户模型中调用了devise方法。也许你已经运行过rails g devise User了？

注释掉它，并注释掉你的路由文件中的devise_for :users行。

Answer 2

完成rails教程&这些答案对我不起作用，但经过一番搜索后找到了解决方案。希望这篇文章能帮助那些遇到这个问题的新手。

Ruby文件转到：config/routes.rb

• 注释掉devise_for :installs (在前面放一个散列标签)

• 转到您的Ruby终端并重新输入：rails generate devise:install

现在Devise应该可以正确安装了&后续的错误应该会消失。

Answer 3

对于由于以下错误而到达此处的人员：

用户不响应“devise”方法。这通常意味着您还没有加载ORM文件，或者加载得太晚了。要修复它，请确保在'config/initializers/devise.rb‘内或在'config/application.rb’(RuntimeError)中定义应用程序之前要求‘devise/ORM/ your’

但是您已经正确地初始化了ORM，它可能与gem相关。我在一个旧的应用程序上也遇到了同样的问题，这是因为它与active_reload gem不兼容。gem active_reload与Rails3.2不兼容，应该删除。active_reload已经被合并到了Rails3.2中，所以可以安全地删除它。
