如果你想使用它,如何解决"你需要为你的Gemfile添加gem'守护进程'"生产模式错误？

Question

我正在尝试正确使用Capistrano和RVM,以便将我的Ruby on Rails 3.2.2应用程序部署到运行Ubuntu 10.04 LTS的远程机器上.它接缝,我解决了我以前的相关问题" RVM -对Linux操作系统Ubuntu Capistrano的整合 ".但是,在部署时,我得到与DelayedJob gem相关的以下错误:

    ...

即使错误解释是"如果你想使用它,你需要将gem文件添加到你的Gem文件中",我已经将daemonsgem 添加到我的Gemfile(从上面的输出中你甚至可以注意到我是"使用守护进程"(1.1) 0.8)"):

...
gem 'delayed_job'
gem 'delayed_job_active_record'
gem 'daemons'
...

那么,问题是什么？我怎么解决这个问题？

在我的deploy.rb档案中,我有:

$:.unshift(File.expand_path('./lib', ENV['rvm_path']))
require 'rvm/capistrano'
set :rvm_ruby_string, 'ruby-1.9.3-p125'
set :rvm_type, :user
require 'bundler/capistrano'
...

PS:终端窗口输出:

 $ ruby -v
 > ruby 1.9.3p125 (2012-02-16 revision 34643) [i686-linux]
 $ which ruby
 > /usr/local/rvm/rubies/ruby-1.9.3-p125/bin/ruby

使用捆绑器运行 script/delayed_job： bundle exec script/delayed_job start
