诊断导轨应用程序资产预编译错误

Question

我不能完全弄清楚为什么我不断收到与我的资产预编译相关的错误。从我已经能够从在线文档中推论出来的，我所需要做的就是将rake预编译任务添加到我的deploy.rb文件中，确保已安装javascript运行时gem，将线路负载“deploy/assets”添加到我的capfile和capistrano应该在运行cap deploy：update时预先编译我的资产服务器端。任何人都可以帮助我诊断我在部署输出中收到的错误消息吗？在此先感谢任何能够帮助我的人！非常感谢！

这是我的部署文件：

$:.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://git@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' 

而且这里是我的Gemfile：

source 'http://rubygems.org' 

gem 'rails', '3.1.3' 

# Bundle edge Rails instead: 
# gem 'rails',  :git => 'git://github.com/rails/rails.git' 

gem 'gravatar_image_tag', '1.0.0.pre2' 
gem 'will_paginate', '~> 3.0.2'

group :development do 
gem 'rspec-rails', '2.6.1' 
gem 'annotate', '2.4.0' 
gem 'faker', '0.3.1' 
end 

group :test do 
gem 'rspec-rails', '2.6.1' 
gem 'webrat', '0.7.1' 
gem 'spork', '0.9.0.rc8' 
gem 'factory_girl_rails', '1.0' 
end 

# Gems used only for assets and not required 
# in production environments by default 
group :assets do 
    gem 'execjs' 
    gem 'therubyracer', :platforms => :ruby 
    gem 'sass-rails', '~> 3.1.5' 
    gem 'coffee-rails', '~> 3.1.1' 
    gem 'uglifier', '>= 1.0.3' 
end 

gem 'jquery-rails' 

# To use ActiveModel has_secure_password 
# gem 'bcrypt-ruby', '~> 3.0.0' 

# Use unicorn as the web server 
# gem 'unicorn' 

# Deploy with Capistrano 
gem 'capistrano'
