根据Said Kaldybaev解决方案，我试过

E:\ruby projects\Hospitium Animal Hospital>rails g devise:install
conflict  config/initializers/devise.rb
Overwrite E:/ruby projects/Hospitium Animal Hospital/config/initializers/devise.
rb? (enter "h" for help) [Ynaqdh] h

a - all, overwrite this and all others

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

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

1. Ensure you have defined default url options in your environments files. Her
e
is an example of default_url_options appropriate for a development environm
ent
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>

如果要在Heroku上部署Rails 3.1，则可能需要设置：

config.assets.initialize_on_precompile = false

在config / application.rb上强制您的应用程序无法访问数据库或在预编译资产时加载模型。

Answer 1

请重新运行这些命令，它可以正常工作

rails g devise:install

rails g devise user

rake db:migrate

Answer 2

那时的回购似乎有问题，https://github.com/ninetwentyfour/Hospitium，现在它的工作正常。
