我遇到了Heroku的问题，当我尝试部署我的应用程序时，它没有运行run assets:precompile而且我没有在本地预编译我的资产，我没有在Git中使用de manifest文件。
我的应用程序正在使用雪松，我跑了
heroku stack
结果是
bamboo-mri-1.9.2
bamboo-ree-1.8.7
* cedar
在我部署的应用程序中，我在Heroku中<link href="/stylesheets/application.css" media="all" rel="stylesheet" type="text/css" /> <link href="/assets/application.css" media="all" rel="stylesheet" type="text/css" />。在本地，当我在命令提示符下运行rails s时，资产很好。
我的应用程序是在Ruby on Rails中完成的。我的config / application.rb
require File.expand_path('../boot', __FILE__)
# Pick the frameworks you want:
# require "active_record/railtie"
require "action_controller/railtie"
require "action_mailer/railtie"
require "active_resource/railtie"
#require "sprockets/railtie"
require "rails/test_unit/railtie"
if defined?(Bundler)
# If you precompile assets before deploying to production, use this line
Bundler.require(*Rails.groups(:assets => %w(development test)))
# If you want your assets lazily compiled in production, use this line
# Bundler.require(:default, :assets, Rails.env)
end

答案 0 :(得分：0)
首先，将以下内容添加到application.rb以启用Heroku上的管道预编译：
# config/application.rb
config.assets.initialize_on_precompile = false
然后，在Heroku控制台中（通过从命令行键入heroku run console通过Heroku Toolbelt访问），使用以下命令手动预编译：
bundle exec rake assets:precompile
最后，通过输入heroku restart重启您的应用 - 您的资产管道应该正确预编译。
<强>更新：
如果上述解决方案仍未设置正确的路径，则您有一个清单文件，导致默认资产路径被标记帮助程序覆盖。您可以通过从manifest.yml目录中删除public/assets/文件，提交更改，然后重新部署到Heroku来解决此问题。
