rake设备有问题:设置

Question

我正在尝试通过放入gem 'devise' , '1.1.2'gemfile并运行来设置设计sudo bundle install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应用程序有什么问题？

我认为主要的问题是你没有使用适当的方式来安装设备.以下是每个设计文档的正确生成器:

#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
