尝试加载工作处理插件时出现"uninitialized constant ActiveSupport::CoreExtensions“

Question

我使用的是Rails 5.0.1。我想运行一个后台进程，独立于我的Rails服务器。我以为工作插件会帮到我-- https://github.com/ascarter/workling。但是，在将此Gem添加到我的Gemfile时

gem 'workling'

然后重新启动我的服务器，我得到了这个错误

Gem Load Error is: uninitialized constant ActiveSupport::CoreExtensions

您在workling repo中发布的最后一次提交是在2008年6月。RubyGems使用的是来自February 2009的一个。无论哪种方式，R.I.P和尝试让它在Rails5应用程序上工作是没有意义的:(我强烈建议检查年轻的和积极维护的gem，如sidekiq，resque，delayed_job或许多其他的。
