我正在尝试部署一个 Rails 应用程序，但我遇到了资产预编译错误。根据生产日志，错误是由名为 screen.css 的“蓝图”css 脚本引起的（如您在下面的错误输出中所见）。然而，根据生产日志，该资产实际上是经过预编译的。我尝试在 application.rb 和 config/environments/production.rb 文件中显式添加 screen.css 和 print.css 到预编译数组，如下所示

config.assets.precompile = %w(screen.css print.css)

但无济于事。我还尝试在本地预编译我的资产并将整个内容推送到服务器。我已经尝试了这里列出的所有建议：blueprint/screen.css 没有预编译 ，这里： blueprint css rails 3.1 help ，同样的问题在这里仍未解决：Ruby on Rails 3.2 编译的资产不起作用

我不知道接下来要尝试什么来解决此错误。任何帮助将不胜感激！下面是日志输出，以及我的部署文件、cap 文件和 application.rb 文件。提前感谢您提出的任何建议！

这是部署后日志文件的一些输出，您可以在其中看到 screen.css 已预编译。错误输出如下：

这是部署文件：

$:.unshift(File.expand_path('./lib', ENV['rvm_path'])) # Add RVM's lib directory to the load path.
require "rvm/capistrano"                  # Load RVM's capistrano plugin.
require "bundler/capistrano"

set :application, "Project"

set :scm, "git"
set :repository,  "ssh://server.example.ca/usr/local/git_root/project.git"
set :user, "deploy"

#set :rvm_bin_path, "/usr/local/rvm/bin"
set :rvm_ruby_string, "ruby-1.9.2-p290@project"
set :normalize_asset_timestamps, false

ssh_options[:forward_agent] = true

set :branch, "master"

set :deploy_via, :remote_cache

# If you aren't deploying to /u/apps/#{application} on the target
# servers (which is the default), you can specify the actual location
# via the :deploy_to variable:
set :deploy_to, "/usr/local/www/sites/project.example.ca/"

set :use_sudo, false

set :domain, 'project.example.ca'

role :app, domain
role :web, domain
role :db,  domain, :primary => true

before "deploy:symlink", "assets:precompile"

namespace :assets do
  desc "Compile assets"
  task :precompile, :roles => :app do
    run "cd #{release_path} && bundle exec rake RAILS_ENV=#{rails_env} assets:precompile"
  end
end

这是我的capfile：

load 'deploy' if respond_to?(:namespace) # cap2 differentiator
Dir['vendor/plugins/*/recipes/*.rb'].each { |plugin| load(plugin) }
load 'config/deploy'
load 'deploy/assets'

这是 application.rb 配置文件：

require File.expand_path('../boot', __FILE__)

require 'rails/all'

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 Arbiterapi
  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 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'

    # Precompile problem assets
    config.assets.precompile = %w(screen.css print.css)

  end
end

我遇到了同样的问题。但事实证明，我丢失的资产被编译成 application.js（因为它合并了所有文件），所以我只需要删除对特定文件的引用（在我的例子中是 webcam.js）。

您的文件已合并到 application.css 等...
