Crontab not executing a Python script?

Question

My python script is not running under my crontab.

I have placed this in the python script at the top:

#!/usr/bin/python

I hav

Answer 1

It's usually because the python used by crontab is different from the one you use in the shell. The easiest way to solve this is:

1. get the python you use in the shell:

$ which python # it may be "python3" or something else /usr/bin/python

2. use that specific python in crontab file:

* * * * * /usr/bin/python test.py

Also want to mention that using env -i /bin/bash --noprofile --norc in the shell lets you have the same environment as the one used by crontab, and this is super helpful to debug.

Answer 2

Try this

* * * * * cd <directory_where_python_file_is> && bin/app etc/app_defaults.yaml

There is some path issue with cron. So when you move to directory with python file, cron works like charm!

Answer 3

I'd got the same problem. Despite the fact that the script executed manually was working, in crontab no options mentioned above were working at all. I've moved my script from /home/user/script_directory/ to /opt/scripts/ and it started to work. Possible cause of the problem should be the access (read) permissions to subfolder located in home directory.
