Question

我正在将Rails 3.0应用程序升级到Rails 4.2。在Rails 3.1中添加资产管道后，我注意到包含资产的gem未添加到Rails.application.config.assets.paths

我将这些宝石添加到我的Gemfile

gem 'jquery-rails'
gem 'jquery-ui-rails'

我希望将这些目录添加到Rails.application.config.assets.paths

 ~/.rbenv/versions/2.2.3/lib/ruby/gems/2.2.0/gems/jquery-ui-rails-5.0.5/app/assets/images
 ~/.rbenv/versions/2.2.3/lib/ruby/gems/2.2.0/gems/jquery-ui-rails-5.0.5/app/assets/javascripts
 ~/.rbenv/versions/2.2.3/lib/ruby/gems/2.2.0/gems/jquery-ui-rails-5.0.5/app/assets/stylesheets
 ~/.rbenv/versions/2.2.3/lib/ruby/gems/2.2.0/gems/jquery-rails-4.0.3/vendor/assets/javascripts

但是，它只显示我app/assets文件夹中的文件夹。这是Rails.application.config.assets的完整输出。我在其他Rails应用程序中具有完全相同的配置，我没有遇到此问题。

您很可能仍然拥有assets中的Gemfile群组。

assets分组概念是Rails 3中的遗物，has been removed in rails 4.0

Rails 4.0从Gemfile中删除了资产组。你需要删除升级时来自Gemfile的那一行。

在我最近从3.0升级到4.0的导轨应用中，包括assets组中的宝石阻止了宝石资产被包含在Rails.application.config.assets.paths中。从Gemfile中删除assets组，并更新捆绑包修复了问题。

具有资产的Rails gem未添加到config.assets.paths
