來自藍圖的資產預編譯錯誤css - ActionView :: Template :: Error（藍圖/ screen.css沒有預編譯） - 內部服務器錯誤500

Question

我試圖部署一個rails應用程序，但我堅持使用資產預編譯錯誤。根據生產日誌，錯誤是由一個名爲screen.css的'Blueprint'css腳本引起的（如您在下面的錯誤輸出中看到的）。但是根據生產日誌，這個資產實際上是預先編譯好的。我試着明確加入screen.css和print.css的預編譯陣列，無論是在application.rb中和配置/環境/ production.rb文件如下

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

，但無濟於事。我也嘗試過在本地預編譯我的資產，並將所有內容推送到服務器。我試着在這裏列出的所有建議：blueprint/screen.css isn't precompiled 這裏： blueprint css rails 3.1 help 和相同的問題仍然沒有得到解決這裏：Ruby on Rails 3.2 compiled assets are not working

我不知道下一步該怎麼嘗試解決此錯誤。任何幫助將非常感激！日誌輸出如下，以及我的部署文件，cap文件和application.rb文件。預先感謝您的任何建議！

以下是部署後日志文件的一些輸出，您可以在其中看到screen.css被預編譯。錯誤輸出如下：

而這裏的部署文件：

$:.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 

這裏是我的capfile：

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

這裏的application.rb中的配置文件：

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

我遇到了同樣的問題。但事實證明，我的遺失資產被編譯到application.js中（因爲它合併了所有文件），所以我只需刪除對特定文件（在我的情況下是webcam.js）的引用。

你的文件被合併到application.css等...
