Question

我正试图像这样重启我的delayed_job工作者：

  task :restart_dj do
    on roles(:app) do
        execute "RAILS_ENV=production #{File.join(current_path,'bin','delayed_job')} restart"
    end
  end

不幸的是，我明白了：

但是，我可以在我的生产控制台上运行RAILS_ENV=production bin/delayed_job restart，没有任何问题。

我正在使用Ruby 2.3.1。

Answer 1

你可以试试https://github.com/AgileConsultingLLC/capistrano3-delayed-job宝石。我个人用它来管理启动，停止和重启。它还处理诸如手动查杀卡住过程等情况。

Answer 2

错误输出告诉您到底出了什么问题：它不明白__dir__的含义。

undefined local variable or method `__dir__' for main:Object

如果你进一步了解堆栈跟踪，原因很明显：

from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'

您正在开发中运行2.3.1，但生产正在使用1.9。如果您在生产中运行多个版本的Ruby，则无法在应用程序代码中正确选择2.3。

使用Capistrano重新启动delayed_job
