【问题标题】：sidekiq - WARN: ArgumentError: wrong number of arguments (given 0, expected 2..3)sidekiq - 警告：ArgumentError：参数数量错误（给定 0，预期 2..3）
【发布时间】：2018-04-19 19:50:22
【问题描述】：

它显示错误数量的参数，但我传递了 3 个参数

ScannerWorker.perform_async('bob1','bob2',5)

这里是sidekiq工人代码

  class ScannerWorker
    include Sidekiq::Worker

  def perform(bob1, bob2, bob3)
    puts bob1
  end
end

sidekiq 版本：- 4.2.7
导轨 4.2.6
Redis 服务器 v=3.0.7

【问题讨论】：

尝试重启 Sidekiq...
并尝试重启 raisl 服务器

标签： ruby-on-rails-4 sidekiq

【解决方案1】：

按照以下步骤操作
* 在 gemfile 中提及 sidekiq 版本
* 杀死sidekiq进程并重启sidekiq

【讨论】：

【解决方案2】：

您需要重新启动 Sidekiq。实时代码重新加载仅适用于运行 Rails 5.0+ 的 Sidekiq 4.2+。

【讨论】：

【解决方案3】：

值得注意。我一直在研究类似的问题。

SomeWorker.perform_async(@user.id)

  class SomeWorker
    include Sidekiq::Worker

  def perform(user_id)
    puts "{user_id}"
  end
end

不确定我收到参数错误的确切原因。可能是因为实例变量，也可能是 Rails 错误。
尽管如此，我还是使用了

 $rails g sidekiq:worker SomeWorker

看到了这个*。

  class SomeWorker
    include Sidekiq::Worker

  def perform(*args)
    puts #some thing
  end
end

通过添加 astrix 一切正常。

快速回答：

 class SomeWorker
    include Sidekiq::Worker

  def perform(*user_id)
    puts #some thing
  end
end
