create config/locales/devise.en.yml

1	==========================================================================

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', port: 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. You can copy Devise views (for customization) to your app by             running:
rails g devise:views
需要针对你的项目，根据提示来进行相应的配置。如果你想要自定义 devise 的页面，需要先生成页面文件，然后进行重写，关于 devise             的定制化在本文的如何定制 devise 章节会介绍。
