Can use python2.7 with Cron

I am using this script to check I can run it in python2.7.

#!/usr/bin/env python2.7
import sys
if __name__ == "__main__":
    print(sys.version)

The script I want to run can not run on python < 2.7

The Crontab line is */1 * * * * $HOME/bin/pythver.py > $HOME/bin/version.txt

It runs if #!/usr/bin/env python2.6 but it does not in any other version.

Can anybody hel me, please?

The short answer is: specify the full path to python2.7 in your script, as in

1	#!/usr/bin/env /usr/local/bin/python2.7

Explanation:

The issue here is that crond will run a script a minimal environment set, thus /usr/local/bin is not in the PATH, hence the python2.7 binary is not found (or any other python version besides 2 and 2.6). You get a minimal environment when running scripts from crond:

SHELL=/bin/sh
MAILTO=
USER=XXXXXX
PATH=/usr/bin:/bin
PWD=/home/XXXXXX
SHLVL=1
HOME=/home/XXXXXX
LOGNAME=XXXXXX
MAILFROM=X@XXXXXX.webfaction.com
_=/usr/bin/env

If you are relying on environmental variables, then you might need to set them explicitly in your script.

Sincerely,

Valentin I.
