Rails 4生成設計視圖

Question

我想為應用程序生成一些設計視圖，但每當我嘗試使用命令rails g devise:views ，我都會遇到一個復雜的錯誤，遠遠超出我的理解。

/Users/michaeldunnegan/.rvm/gems/ruby-2.0.0-p247/gems/railties-4.0.0/lib/rails/application/routes_reloader.rb:10:in `rescue in execute_if_updated': Rails::Application::RoutesReloader#execute_if_updated delegated to updater.execute_if_updated, but updater is nil: #<Rails::Application::RoutesReloader:0x007ff613f5bb10 @paths=["/Users/michaeldunnegan/projects/SoundShare/config/routes.rb"], @route_sets=[#<ActionDispatch::Routing::RouteSet:0x007ff6168369e0>]> (RuntimeError)

    from bin/rails:4:in `<main>'

其中一行，/ /Users/michaeldunnegan/projects/SoundShare/config/environment.rb:4:in

很有意思 我在該文件中的所有內容是：

# Load the Rails application.
require File.expand_path('../application', __FILE__)

SoundShare::Application.initialize! # this is the line

Answer 1

1. 請確保您有devise與軌道4兼容的寶石gem 'devise', '~> 3.0.0.rc' #or higher

2. 運行bundle update

3. 在initializers刪除devise.rb ，然后再次運行devise.rb devise:install以在初始化程序中安裝新配置。

4. 確保你運行devise模型生成器，例如rails g devise User

5. 現在你應該能夠運行： rails g devise:views

編輯

在Mike的計算機上使用teamviewer工作后，我們從rails 4上的一個工作項目中devise.rb的副本並將其放在config/initializers/

接下來我們運行了rails generate devise:install命令，它說了一些關於棄用的內容，並詢問我們是否要替換devise.rb文件的內容。 我們接受了它，在此之后所有設計命令都運行良好。
