耙资产：预编译停滞 [英] rake assets:precompile stuck

问题描述

几天前我发现jquery日历不适用于我的部署站点（heroku）。在挖掘问题我注意到，我的开发服务器上的网站的源有大约100个脚本标签与bootstrap（我使用twitter引导程序的CSS），但在prod服务器上。我有4个脚本标签。在搜索时，我发现我应该在资产管道的rails控制台上运行 rake assets：precompile 。但是运行时间非常长，上次花了6个小时，我不得不放弃它。

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 和 config.assets.compile 到 true 。但问题仍然存在。我也尝试从 gem 中删除​​ jquery-rails / jquery-ui-rails ，但问题仍然存在。
这里是我的 config / environmnets / production.rb

  ProductRecall :: Application.configure do 
＃此处指定的设置优先于config / application.rb中的设置

＃禁用Rails的静态资产服务器（Apache或nginx已经这样做）

＃压缩JavaScript和CSS 
 config.assets.compress = true 
 
＃如果预编译的资产不存在，则不要回退到资产管道

 end 
  

让我知道这里有什么问题。因为2天以来我一直没有线索

解决方案

我也面临同样的问题。其实宝石会发生冲突。这里的'rufus-scheduler'宝石是罪魁祸首。尝试删除宝石并部署。

接下来您可以试试这个

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

couple of days ago i noticed that jquery calendar is not working on my deployment site(heroku). on digging out the problem i noticed that source of site on my dev server has some 100 script tags related to bootstrap(i am using twitter bootstrap css) but on prod server. i have 4 script tags. on searching i found that i should run rake assets:precompile on my rails console fo asset pipeline. but while running it is taking terribly long time, last time it took 6 hours and i had to abort it.

referring to many sites and post, i found that i should change config.serve_static_assetsto true and config.assets.compile to true. but problem is still there. i also tried to remove jquery-rails/jquery-ui-rails from gembut problem is still there. here is my 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

my config/application.rb looks like this

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

here is my Gem file:

end

group :assets do
  gem 'sass-rails',   '3.2.5'

  gem 'database_cleaner', '0.7.0'
end

#gem 'jquery-ui-rails'

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

plz let me know what is wrong here. as i am terribly stuck with no clue since 2 days

解决方案

I had also faced the same problem. Actually gem gets conflict. Here 'rufus-scheduler' gem is the culprit. Try to remove the gem and deploy.

Next you can try this

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
