使用脚本/delay_job创建delayed_job工作程序时发生未定义的方法错误 [英] Undefined Method Error when creating delayed_job workers with script/delay_job

问题描述

运行多个工作程序时遇到问题.

Having a bit of a problem running multiple workers.

使用rake jobs:work作业创建工作程序时，即使没有多次调用，运行也不会出现问题，但是使用ruby script/delayed_job -n 5 start all作业创建工作程序时，由于在Syck::DomainType上使用未定义的方法而失败.

When creating workers with rake jobs:work jobs run without and problem, even when invoking it multiple times, but when creating workers with ruby script/delayed_job -n 5 start all jobs fail with undefined method on Syck::DomainType.

我已经搜索了很多，但是似乎找不到解决方案.我在Mongoid后端上运行DelayedJob.宝石版本:

I've searched quite a bit, but can't seem to find the solution for this. I am running DelayedJob on the Mongoid backend. Gem versions:

• 0.9.2耙
• rails 3.0.6
• delayedjob 2.1.4
• delayedjob_mongoid 1.0.2

有人遇到类似的错误/有解决方案吗?还是缺少一些信息，说明为什么/如何根据调用工人的方式来不同地创建工人?

Has anyone experienced a similar error/have a solution? Or short of that some information on why/how workers are being created differently depending on which way they are invoked?

推荐答案

问题似乎出自捆绑程序> = 1.0.10，如果存在libyaml，则加载psych并覆盖一些sycks功能.我能够从系统中删除libyaml安装，但我知道并非所有人都能做到.很难追踪，希望这篇文章能对其他人有所帮助

It looks like the problem was derived from bundler >= 1.0.10 loading up psych and overwriting some of sycks functionality if libyaml is present. I was able to remove the libyaml install from my system, something that I know won't be possible for everyone. Tough to track down, hopefully this post will help someone else
