Heroku + DelayedJob未能通过“ rake jobs：work”和“ heroku worker 1”

如何解决Heroku + DelayedJob未能通过“ rake jobs：work”和“ heroku worker 1”

我无法在已验证的heroku帐户上排队等待delay_jobs运行。这是细分： 当我在heroku上调用delay_job时

# tropo_controller.rb in app/controllers
class TropoController < ApplicationController
  require \'lib/event_job\'

  ...

  def sms
    Delayed::Job.enqueue(EventJob.new(nil))

然后验证delay_job存在

$ heroku console
>> Delayed::Job.all

[#<Delayed::Backend::ActiveRecord::Job id: 2,priority: 0,attempts: 0,handler: \"--- !ruby/struct:EventJob \\nevent_id: \\n\",last_error: nil,run_at: \"2011-05-30 21:01:24\",locked_at: nil,failed_at: nil,locked_by: nil,created_at: \"2011-05-30 21:01:24\",updated_at: \"2011-05-30 21:01:24\">]

并尝试以这种方式开始新工作

$ heroku rake jobs:work
Starting job worker

(hangs)

或者这样

$ heroku workers 1
/Users/jaimeohm/.rvm/gems/ruby-1.9.2-p0@rails303/gems/heroku-2.2.1/lib/heroku/command.rb:125:in `rescue in run\': undefined local variable or method `args\' for Heroku::Command:Module (NameError)
    from /Users/jaimeohm/.rvm/gems/ruby-1.9.2-p0@rails303/gems/heroku-2.2.1/lib/heroku/command.rb:116:in `run\'
    from /Users/jaimeohm/.rvm/gems/ruby-1.9.2-p0@rails303/gems/heroku-2.2.1/bin/heroku:14:in `<top (required)>\'
    from /Users/jaimeohm/.rvm/gems/ruby-1.9.2-p0@rails303/bin/heroku:19:in `load\'
    from /Users/jaimeohm/.rvm/gems/ruby-1.9.2-p0@rails303/bin/heroku:19:in `<main>\'

它失败。我运行“ 4”，重置数据库，然后重新启动服务器，但仍然失败。我故意清空排队作业的执行方法

# event_job.rb in app/lib
class EventJob < Struct.new(:event_id)
  def perform
    # empty for now
  end
end

我想念什么？     

解决方法

        Heroku现在已经从heroku gem v2.2.2开始修复了该错误。
