我是 Ruby on Rails 的新手，我尝试从 Internet 上做一些示例。但是当我尝试生成设计安装时出现错误。我通过添加gem devise 修改了 Gemfile 。然后运行：

bundle install

但是当我跑步时。

rails generate devise:install

我有下一个错误：

/usr/local/lib/ruby/gems/0.9.1/gems/devise-1.1.3/lib/devise.rb:193:in `mailer=': undefined method `ref' for ActiveSupport::Dependencies:Module (NoMethodError)

Devise 的版本比较老。

你可以做：

bundle update devise

接着：

bundle install

这应该升级设计 gem。

你可以试着把它放在你的里面Gemfile而不是仅仅gem 'devise'

gem 'devise', github: 'ghiculescu/devise', branch: 'patch-2'

重新运行bundle install

然后你可以做rails generate devise:install

它应该是：

rails generate devise_install

并不是：

rails generate devise:install
