Question

我想开始使用resque。所以我创建了三个文件，一个用于创建虚拟作业，另外两个用于处理它：


    --- image_transformer.rb ---
    # coding: UTF-8
    class ImageTransformer
      @queue = 'image_transform_queue'

      def self.perform(asset_id)
        puts "perform"
        puts asset_id
      end
    end


    --- create_job.rb ---
    # coding: UTF-8
    require 'resque'
    require_relative 'image_transformer'

    Resque.enqueue(ImageTransformer, 'test')


    --- Rakefile ---
    # coding: UTF-8
    require_relative 'image_transformer'
    require 'resque/tasks'

然后我首先执行$ ruby create_job.rb而没有问题。我可以在resque队列中看到这份工作。

现在我想开始一个工人 - 但是失败了：


    $ QUEUE=* VVERBOSE=1 VERBOSE=1 rake resque:work --trace

有人知道发生了什么吗？它看起来像是一些编码问题，但在哪里呢？

我使用的是Windows 7（如果相关的话）。

编辑：我将调试输出插入'#encode'方法： {：queue =＆gt;“image_transform_queue”，：run_at =＆gt;“2012/03/28 13:25:53 Mitteleurop \ xE4i sche Sommerzeit“，：payload =＆gt; {”class“=＆gt;”ImageTransformer“，”args“=＆gt; [”test“]}}

显然问题是“：run_at”值包含一个德语变音符号（这是我的语言环境）。

将其从未答复的清单中删除：

我将调试输出插入'#encode'方法：

{
    :queue=>"image_transform_queue",
    :run_at=>"2012/03/28 13:25:53 Mitteleurop\xE4i sche Sommerzeit",
    :payload=>{"class"=>"ImageTransformer", "args"=>["test"]}
}

显然问题是:run_at值包含德语变音符号（这是我的语言环境）。

rake resque：工作失败，简单的例子
