蓝图CSS中的资产预编译错误-ActionView :: Template :: Error（未预编译blueprint / screen.css）-内部服务器错误500

Question

我正在尝试部署Rails应用程序，但遇到了资产预编译错误。 根据生产日志，该错误是由名为“ screen.css”的“蓝图” css脚本引起的（如下面的错误输出中所示）。 但是，根据生产日志，实际上确实对该资产进行了预编译。 我尝试在application.rb和config / environments / production.rb文件中将screen.css和print.css显式添加到预编译数组中，如下所示

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

但无济于事。 我还尝试过在本地预编译资产，然后将整个内容推送到服务器。 我已经尝试过这里概述的所有建议： blueprint / screen.css尚未预编译，并且在这里： blueprint css rails 3.1 help ，而这里仍未解决相同的问题： Ruby on Rails 3.2编译后的资产无法正常工作

我不知道下一步该怎么解决该错误。 任何帮助将不胜感激！ 下面是日志输出，以及我的部署文件，帽文件和application.rb文件。 预先感谢您的任何建议！

这是部署后日志文件的一些输出，您可以在其中看到screen.css已被预编译。 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

Answer 1

我遇到了同样的问题。 但是事实证明，我丢失的资产已编译到application.js中（因为它合并了所有文件），因此我只需要删除对特定文件的引用（在我的情况下为webcam.js）。

您的文件已合并到application.css等中...
