在Mac中运行crontab [英] Running crontab in mac

问题描述

我正在尝试测试必须由cron作业运行的python脚本.我正在尝试在Mac中配置cron作业，但无法运行.这是我的计划工作...

I'm trying to test a python script that has to be run by a cron job. I'm trying to config the cron job in my mac but doesn't run. Here is my cron job...

*   *   *   *   *   user /usr/local/bin/python3 ~/Documents/wpc/stocks/daily_stock.py

如果我 crontab -l <​​/code>，工作就在那里.我手动运行了脚本并可以正常运行，但不能由cron作业运行.我该如何解决?

If I crontab -l the job is there. I ran the script manually and works but is not running by the cron job. How can I fix this?

推荐答案

我使用以下方法在Mac OS上解决了此问题.

I used the following method to solve this issue on Mac OS.

您可以在Python脚本的顶部添加一个shebang以指定Python版本路径:

You can add a shebang to the top of your python script to specify the Python versions path:

Python 3

#!/usr/bin/env python3

Python 2.7

#!/usr/bin/env python2

您还需要确保文件是可执行文件:

chmod a+x filename.py

这将允许您执行python脚本，而不必在脚本之前指定"python".

This will allow you to execute the python script without having to specify "python" before the script.

然后可以使用 crontab -e 设置crontab，例如:

You can then set your crontab with crontab -e, e.g:

0 9/15 * * *  cd /Users/user12/Dev/Scripts/Python && ./test.py
