问题
I have a python script, script.py, and am using cron to run this script periodically. The script runs as expected, but once the cron job finishes, I get the following error in /var/mail/[myusername]:
sh: sysctl Command Not Found
The following is the cron job:
0 14 * * * PATH=$PATH:/usr/sbin PYTHONPATH=/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/ /usr/bin/python2.7 ~/.../script.py
I was told to include both PATH and PYTHONPATH in the task (as before, python wouldn't recognize several modules I had imported and had installed), so at this point, I'm not sure what the problem could be
回答1:
On some Macs, sysctl is located in /sbin/ instead of /usr/sbin/. You should add /sbin to your PATH variable
