我正在使用 Rails 5.0.1。我想运行一个独立于我的 Rails 服务器的后台进程。我认为工作插件会帮助我 - https://github.com/ascarter/workling。但是，将这个 Gem 添加到我的 Gemfile

gem 'workling'

并重新启动我的服务器，我收到此错误

workling您发布的最后一次提交是在 2008 年 6 月。RubyGems使用的是从2009 年 2 月开始的。无论哪种方式，RIP 并且尝试使其与 Rails 5 应用程序一起工作是没有意义的 :( 我强烈建议检查年轻且积极维护的 gem，例如sidekiq、resque、delayed_job或许多其他。
