我是 Rails 新手，无法查明问题所在。我正在关注关于设计的 RailsCast 教程 #209，运行时出现错误：rails g devise:views

这是错误：

我更改了 ruby​​ 的版本以查看是否可以解决问题，但我无法找到确切的问题。有没有其他人遇到过这个错误？

看起来您缺少一些需要完成的手动设置（正如@dougui 和@janders223 指出的那样，这很可能是您的路线），在您完成运行后立即打印在控制台上rails generate devise:install：

===============================================================================

Some setup you must do manually if you haven't yet:

  1. Ensure you have defined default url options in your environments files. Here 
     is an example of default_url_options appropriate for a development environment 
     in config/environments/development.rb:

       config.action_mailer.default_url_options = { :host => 'localhost:3000' }

     In production, :host should be set to the actual host of your application.

  2. Ensure you have defined root_url to *something* in your config/routes.rb.
     For example:

       root :to => "home#index"

  3. Ensure you have flash messages in app/views/layouts/application.html.erb.
     For example:

       <p class="notice"><%= notice %></p>
       <p class="alert"><%= alert %></p>

  4. If you are deploying Rails 3.1 on Heroku, you may want to set:

       config.assets.initialize_on_precompile = false

     On config/application.rb forcing your application to not access the DB
     or load models when precompiling your assets.
