Cron Job Errors帮助-Rails Runner错误

问题描述

|

* * * * * /bin/bash -l -c \'cd /Users/boris/projects/MyApp/ && rails runner \"Resque.enqueue(Place)\"\'

基本上，我需要执行以下操作： 用RVM加载Ruby 导航到

MyApp

Dir 运行以下行：

rails runner \"Resque.enqueue(Place)

上面的cron似乎正在运行，但是它会在rails运行程序中产生以下错误 这是怎么回事？

解决方法

实际上，执行此操作的最佳方法是使用rvm包装器。您可以这样创建一个包装器：

rvm wrapper ruby-1.9.3-p0@somegemset appname rails 

二进制文件可以是rails，rake，gem或其他已安装的红宝石二进制文件。发生的情况是rvm创建了一个包装器，该包装器将在执行rails命令之前提供正确的rvm环境。在系统范围的rvm上，通常将包装器放在/ usr / local / rvm / bin / 现在，从cron您可以执行以下操作：

*/3 * * * * cd /path/to/your/app && appname_rails runner \"Resque.enqueue(Place)\" -e production

这将进入您的应用程序目录，并每3分钟执行一次刚刚创建的rvm包装器。本示例基于rails 3和生产环境。     ,在运行任何Ruby代码之前，您需要通过RVM提供正确的环境。因此，在命令中包含以下内容：

source /usr/local/rvm/environments/ruby-1.9.2-p180@my-gemset

因此，潜在的解决方案是：

SHELL=/bin/bash
* * * * * source /{path_to_rvm_environment_for_ruby}@{gemset} && cd /Users/boris/projects/MyApp/ && rails runner \"Resque.enqueue(Place)\"\'

    ,这里有很多动人的部分，这里有一些关于要检查您的环境（红宝石，rvm，捆绑软件）的指针-发布您的发现，然后从那里去。 捆绑器的路径问题，要更改还是不更改？ 捆绑错误 我猜命令在cron外部运行正常吗？如果您以其他用户身份运行cron作业，请检查该用户的环境。
