Question

几天前我注意到jquery日历在我的部署站点（heroku）上不起作用。在挖掘问题时，我注意到我的开发服务器上的网站源代码有100个与bootstrap相关的脚本标签（我使用的是twitter bootstrap css），但是在prod服务器上。我有4个脚本标签。在搜索时我发现我应该在我的rails控制台上运行rake assets:precompile资产管道。但是在运行它的时间非常长，上次花了6个小时我不得不中止它。

指的是很多网站和帖子，我发现我应该将config.serve_static_assets更改为true，将config.assets.compile更改为true。但问题仍然存在。我还尝试从jquery-rails/jquery-ui-rails删除gem，但问题仍然存在。这是我的config/environmnets/production.rb

ProductRecall::Application.configure do
  # Settings specified here will take precedence over those in config/application.rb

  # Code is not reloaded between requests
  config.cache_classes = true

  # Full error reports are disabled and caching is turned on
  config.consider_all_requests_local       = false
  config.action_controller.perform_caching = true

  # Disable Rails's static asset server (Apache or nginx will already do this)
  config.serve_static_assets = true

  # Compress JavaScripts and CSS
  config.assets.compress = true

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

  # Generate digests for assets URLs
  config.assets.digest = true



  # Specifies the header that your server uses for sending files
  # config.action_dispatch.x_sendfile_header = "X-Sendfile" # for apache
   config.action_dispatch.x_sendfile_header = 'X-Accel-Redirect' # for nginx

  # Force all access to the app over SSL, use Strict-Transport-Security, and use secure cookies.
  config.force_ssl = true

  # Enable locale fallbacks for I18n (makes lookups for any locale fall back to
  # the I18n.default_locale when a translation can not be found)
  config.i18n.fallbacks = true

  # Send deprecation notices to registered listeners
  config.active_support.deprecation = :notify

  # Log the query plan for queries taking more than this (works
  # with SQLite, MySQL, and PostgreSQL)
  # config.active_record.auto_explain_threshold_in_seconds = 0.5

  config.action_controller.perform_caching  = false
end

我的config/application.rb看起来像这样

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 ProductRecall
  class Application < Rails::Application

    # Configure the default encoding used in templates for Ruby 1.9.
    config.encoding = "utf-8"

    # Configure sensitive parameters which will be filtered from the log file.
    config.filter_parameters += [:password]

    # Enable escaping HTML in JSON.
    config.active_support.escape_html_entities_in_json = true

    # 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'
    config.action_mailer.default_url_options = { host: 'localhost:3000' }
  end
end

这是我的Gem文件：

source 'https://rubygems.org'

gem 'rails', '3.2.13'
gem 'bootstrap-sass', '2.1'
gem 'bcrypt-ruby', '3.0.1'
gem 'therubyracer', :platforms => :ruby, :platforms => :ruby
gem 'faker', '1.0.1'
gem 'will_paginate', '3.0.3'
gem 'bootstrap-will_paginate', '0.0.6'
gem 'bootstrap-datepicker-rails'
gem "google_visualr", "~> 2.1.0" 
gem 'twitter-bootstrap-rails'
gem "galetahub-simple_captcha", :require => "simple_captcha"
gem 'rufus-scheduler'

group :development, :test do
  gem 'sqlite3', '1.3.5'
  gem 'rspec-rails', '2.11.0'
end

group :development do
  gem 'annotate', '2.5.0'
end

group :assets do
  gem 'sass-rails',   '3.2.5'
  gem 'coffee-rails', '3.2.2'
  gem 'uglifier', '1.2.3'
end

gem 'jquery-rails', '2.0.2'

group :test do
  gem 'capybara', '1.1.2'
  gem 'factory_girl_rails', '4.1.0'
  gem 'cucumber-rails', '1.2.1', :require => false
  gem 'database_cleaner', '0.7.0'
end

#gem 'jquery-ui-rails'

group :production do
  gem 'pg', '0.12.2'
end

请告诉我这里有什么问题。因为我从2天开始就没有任何线索了。

我也面临同样的问题。实际上宝石会发生冲突。这里的'rufus-scheduler'宝石是罪魁祸首。尝试删除gem并进行部署。

接下来你可以试试这个

task :precompile, :roles => :web, :except => { :no_release => true } do 
  run_locally("rm -rf public/assets/*") 
  run_locally("bundle exec rake assets:precompile") 
  servers = find_servers_for_task(current_task) 
  port_option = port ? " -e 'ssh -p #{port}' " : '' 
  servers.each do |server| 
    run_locally("rsync --recursive --times --rsh=ssh --compress -- 
    human-readable #{port_option} --progress public/assets #{user} @#{server}:         {shared_path}") 
  end 
end
