Question

我正在使用rails 4.2并使用Windows 7 64位开发我的rails应用程序，一切都在开发模式下工作正常，但一旦我试图在生产模式下运行我的应用程序，我的应用程序布局，CSS和JavaScript都破了，我相信它与资产管道有关，但我不太明白，请给我一些帮助。

这是

下的资产结构

vendor/assets
 - public_assets
   - font
   - img
     - bg
     - favicon
     - images
         - proteam
     - png
         - ualanding
     - portofolio
         - thumbnail
         - fullsize
   - css
   - js
   - sass
   - vendor
      - bootstrap
         - css
         - fonts
         - js
      - font-awesome
         - css
         - fonts
         - less 
         - scss
      - jquery
      - magnific-popup
      - ninja-slider
      - scroolreveal
   - vid
 - Static_Dev
   - assets
      - img
         - flags
         - avatars
     - css
     - js 
          - libs
          - views
     - fonts

我在这些文件中调用了我的资产：

admin.css
admin.js
public.css
public.js

我还将此添加到我的assets.rb：

Rails.application.config.assets.precompile += %w( public.css )
Rails.application.config.assets.precompile += %w( admin.css )
Rails.application.config.assets.precompile += %w( admin.js )
Rails.application.config.assets.precompile += %w( public.js )

，这是application.rb

config.assets.paths += Dir["#{Rails.root}/vendor/public-assets/*"].sort_by { |dir| -dir.size }
config.assets.paths += Dir["#{Rails.root}/vendor/Static_Dev/*"].sort_by { |dir| -dir.size }

这是我的浏览器错误日志：

我运行此命令：

rake assets：预编译RAILS_ENV =生产

和结果错误如下：

C:\Users\lenovo\Documents\urbanace\urbanacecode>rake assets:precompile RAILS_ENV
=production

请告诉我错过了什么？

Answer 1

打开config / environments / production.rb并确保将以下选项设置为true：

# Don't fallback to assets pipeline if a precompiled asset is missed
config.assets.compile = true

然后运行：

rake assets:precompile --trace RAILS_ENV=production

希望这有帮助！

Rails资产，css，javascript都在生产模式上破坏了吗？
