问题描述

我正在尝试从 cron 运行 python 脚本，但它没有正常运行，所以我假设它的路径环境变量不同.无论如何要更改python脚本中的变量吗?

I'm trying to run a python script from cron, but its not running properly so I'm assuming its the different path env variable. Is there anyway to change the variable within a python script?

解决方案

您不需要在 python 脚本中设置 PATH.相反，放一些类似

You shouldn't need to set the PATH from within the python script. Instead, put something like

USER=joe HOME=/home/joe SHELL=/bin/bash PATH=/sbin:/bin:/usr/sbin:/usr/bin:/some/other/path PYTHONPATH=/home/joe/pybin MAILTO=joe LANG=en_US.UTF-8 #min hr day mon dow */5 12 * * * reminder.py 'Eat lunch'

在您的 crontab 顶部.然后，这些环境变量将可用于通过您的 crontab 运行的所有 cron 作业.

at the top of your crontab. These environment variables will then be available to all cron jobs run through your crontab.
