我在使用 Heroku 时遇到问题，当我尝试部署我的应用程序时，它没有运行 run assets:precompile而且我还没有在本地预编译我的 Assets ，我在 Git 中没有 list 文件。

我的应用程序正在使用 cedar，我运行 heroku stack

结果是
bamboo-mri-1.9.2<br/>
bamboo-ree-1.8.7<br/>
* cedar

在我部署的应用程序中，我得到 <link href="/stylesheets/application.css" media="all" rel="stylesheet" type="text/css" />代替 <link href="/assets/application.css" media="all" rel="stylesheet" type="text/css" />在英雄库。在本地，当我运行 rails s在命令提示符下 Assets 没问题。

我的应用程序是用 Ruby on Rails 制作的。我的配置/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

module Mongoapp
  class Application < Rails::Application
    # Settings in config/environments/* take precedence over those specified here.
    # Application configuration should go into files in config/initializers
    # -- all .rb files in that directory are automatically loaded.

    # Custom directories with classes and modules you want to be autoloadable.
    # config.autoload_paths += %W(#{config.root}/extras)

    # Only load the plugins named here, in the order given (default is alphabetical).
    # :all can be used as a placeholder for all plugins not explicitly named.
    # config.plugins = [ :exception_notification, :ssl_requirement, :all ]

    # Activate observers that should always be running.
    # config.active_record.observers = :cacher, :garbage_collector, :forum_observer

    # Set Time.zone default to the specified zone and make Active Record auto-convert to this zone.
    # Run "rake -D time" for a list of tasks for finding time zone names. Default is UTC.
    # config.time_zone = 'Central Time (US & Canada)'

    # The default locale is :en and all translations from config/locales/*.rb,yml are auto loaded.
    # config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}').to_s]
    # config.i18n.default_locale = :de

     config.time_zone = 'Bogota'

    # like if you have constraints or database-specific column types
    # config.active_record.schema_format = :sql

    # Enforce whitelist mode for mass assignment.
    # This will create an empty whitelist of attributes available for mass-assignment for all models
    # in your app. As such, your models will need to explicitly whitelist or blacklist accessible
    # parameters by using an attr_accessible or attr_protected declaration.
    # config.active_record.whitelist_attributes = true

    # Enable the asset pipeline
    config.assets.enabled = true


    # Version of your assets, change this if you want to expire all your assets
    config.assets.version = '1.0'

最佳答案

首先，将以下内容添加到您的 application.rb 以在 Heroku 上启用管道的预编译:

# config/application.rb
config.assets.initialize_on_precompile = false

然后，在您的 Heroku 控制台中(可通过 Heroku Toolbelt 从命令行键入 heroku run console 访问)，使用以下命令手动预编译:

bundle exec rake assets:precompile

最后，通过键入 heroku restart 重新启动您的应用程序 - 您的 Assets 管道应该已正确预编译。

更新:

如果上述解决方案仍未设置正确的路径，则您的 list 文件导致默认 Assets 路径被标签助手覆盖。您可以通过从 public/assets/ 目录中删除 manifest.yml 文件来解决此问题，提交您的更改，然后重新部署到 Heroku。
