我已经更新了我的项目以使用ruby 2.2.1，这应该在Rails 3.2.22上得到支持（参见http://weblog.rubyonrails.org/2015/6/16/Rails-3-2-22-4-1-11-and-4-2-2-have-been-released-and-more/）
我的delayed_jobs坏了：
class Feedback
TestJob = Struct.new(:id) do
def perform
puts "test job running #{id}"
end
def self.run_test_job
Delayed::Job.enqueue TestJob.new(1)
end
end
在rails控制台（开发）中，我Feedback.run_test_job
让工作人员运行rake jobs:work
我得到了这个
[Worker(host:pro-vincent.home pid:62850)] Starting job worker
[Worker(host:pro-vincent.home pid:62850)] Job Feedback::TestJob (id=39) RUNNING
应打印test job running 1。我用ruby 2.1.1测试过，它工作正常。
我错过了什么让它起作用？
