【问题描述】：

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。然后错误出来了，有谁知道我的 Rails 3 应用出了什么问题？

顺便问一下，谁能教我如何从 github 阅读文档？比如像github.com/plataformatec/devise/wiki/_pages这样的网站

【解决方案1】：

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
