Question

我的所有cron作业都出错了，日志是：该错误不会影响我的Web应用程序，但会影响我的后台作业。它似乎在我的系统上出错，但不知道如何解决它。有两个版本的json，我试图卸载它，但json-1.8.1不能，因为它是默认的。请帮忙。谢谢！

Answer 1

如果没有看到有问题的cron工作，很难发表评论。你正在使用RVM;你是不是可以在你的cron工作中调用正确的红宝石？如果你不是，那就解释了为什么你的网络应用程序工作正常，但你的后台工作失败了。

Missing required gems when execute cron created by whenever gem in production environment

Answer 2

我建议将whenever gem用于cron任务。我发现处理gem版本更加可靠，然后你不必担心系统宝石。这应该为你解决问题（我希望）。

Answer 3

我所有的cron工作现在都在工作。我发现我当前的rvm环境没有在crontab -e上列出。但是，我不知道为什么这条路可能导致上次一切正常。顺便说一句，

我得到了：

First (get path):
`rvm env --path`
Sencondly (add the path like):
`PATH="/root/.rvm/environments/ruby-2.2.0:...."`
Lastly (I updates some Gem version in Gemfile like mysql2 ... then bundle install)

最终，所有后台工作都在重新开始。
