ruby-on-rails - rake devise :setup 有问题

Question

我正在尝试通过将 gem 'devise' , '1.1.2' 放入 gemfile 并运行 sudo bundle install 来设置设计，然后我尝试运行 rake --trace devise:setup。然后出现错误，有人知道我的 Rails 3 应用程序出了什么问题吗？

我认为主要问题是您没有使用适当的方式来安装设计。以下是符合 devise documentation: 的正确生成器

#this installs the devise initializer which is needed to run devise in r3. 
rails generate devise:install

#this generates your model as a devise resource
rails generate devise [MODEL_NAME]

#this copies all the view files into your local app for modifications
rails generate devise:views
