部署 – Capistrano编译资产错误 – 资产：预编译：非文化？

* executing "cd /home/deploy/tomahawk/releases/20120208222225 && bundle exec rake RAILS_ENV=production RAILS_GROUPS=assets assets:precompile"

我在这里试过尝试编译资产的解决方案：http://lassebunk.dk/2011/09/03/getting-your-assets-to-work-when-upgrading-to-rails-3-1/

在这里：http://dev.af83.com/2011/09/30/capistrano-rails-3-1-assets-can-be-tricky.html

这是我的deploy.rb：

require "bundler/capistrano"
load 'deploy/assets'

set :default_environment,{
 'PATH' => "/opt/ruby/bin/:$PATH"
}

set :application,"tomahawk"
set :repository,"repo_goes_here"
set :deploy_to,"/home/deploy/#{application}"
set :rails_env,'production'
set :branch,"master"

set :scm,:git
set :user,"deploy"
set :runner,"deploy"
set :use_sudo,true

role :web,"my_ip"                         
role :app,"my_ip"                        
role :db,"my_ip",:primary => true 

set :normalize_asset_timestamps,false
after "deploy","deploy:cleanup"

namespace :deploy do
    desc "Restarting mod_rails with restart.txt"
    task :restart,:roles => :app,:except => { :no_release => true } do
        run "touch #{current_path}/tmp/restart.txt"
    end

    [:start,:stop].each do |t|
        desc "#{t} task is a no-op with mod_rails"
        task t,:roles => :domain do ; end
    end
end

task :after_update_code do  
run "ln -nfs #{deploy_to}/shared/config/database.yml #{release_path}/config/database.yml"
end
