如何修改python脚本中的系统路径变量? [英] how do I modify the system path variable in python script?

问题描述

我正在尝试从 cron 运行 python 脚本，但它运行不正常，所以我假设它的路径 env 变量不同.无论如何要更改python脚本中的变量?

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?

推荐答案

您不需要在 Python 脚本中设置 PATH.相反，把类似的东西

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'

在你的 crontab 的顶部.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.
