我有一个ruby sinatra应用程序，它有一个rake任务，它将使用活动记录来检查数据库中的数据文件。我使用when gem来按计划运行这个rake任务。这工作很好，一段时间后，几天后它会失败，看起来它无法写入日志文件。我有一个救援，将通过电子邮件发送我的错误和堆栈跟踪，这就是我得到：Ruby Crontab Rake任务失败，但只有当命令由crontab运行时

每当宝石看起来像这样由创建的crontab中：
0 0,12 * * * /bin/bash -l -c 'cd /home/deployer/public/fulfillment_api/releases/20131010141756 && RACK_ENV=production bundle exec rake background_jobs:process_and_email['\''[email protected]'\''] --silent'
是什么奇怪的是，当我将这个命令放到命令行中时，它运行良好。即使我将用户切换到root并运行它，它仍然可以毫无问题地运行。我只在crontab运行时发生错误。
当“crontab”作业运行时，“PATH”的设置与刚刚登录时不同。您需要确保在cron作业中设置所需的'PATH'项目。 – lurker
嗨@mbratch，感谢您的评论。我尝试将PATH设置为我登录时的相同值，但仍得到相同的结果。 – khartnett
当你在命令行上运行它时，你是用'/ bin/bash ...'来做它吗？ – lurker
