cronjob中的python多线程问题没有执行

Question

I have one script.py which calls other multiprocessing scripts as follows my scripts.py:

import os
from multiprocessing import Pool

scriptspy = [
    '/pyscripts/apoiont01.py',
    '/pyscripts/access.py',
    '/pyscripts/dental.py',
    '/pyscripts/cremers.py',
    '/pyscripts/delcuritib.py',
    '/pyscripts/dtalndes.py',
    '/pyscripts/lobo.py',
    '/pyscripts/ierre.py',
    '/pyscripts/daster.py',
    '/pyscripts/dsul.py',
    '/pyscripts/doema.py',
    '/pyscripts/maz.py',
    '/pyscripts/deura.py',
    '/pyscripts/der.py',
    '/pyscripts/dlo.py',
    '/pyscripts/deoltda.py',
    '/pyscripts/dpeed.py',
    '/pyscripts/derr.py',
    '/pyscripts/dweb.py',
]


def roda_processo(processo):
    os.system('python3.7 {}'.format(processo))


for s in scriptspy:
    roda_processo(s)

My crontab -e:

* * * * 1,5 /usr/local/bin/python3.7 /pyscripts/scripts.py > /pyscripts/logs/scripts.log

Funny thing is, if I run that same manual run command on the terminal: / usr / local / bin / python3. 7 /pyscripts/scripts.py > / pyscripts/logs / scripts.log / usr / local / bin / python3. 7 /pyscripts/scripts.py > / pyscripts/logs / scripts.log it runs normally.

Log /var/log/cron.log: https://gist.githubusercontent.com/braganetx/a05c8b7257df79305dd1b79008323011/raw/8aec453a74566e8872608d1705f05004c1e12e5e/log

You should replace this with the version with the full path to the python interpreter, because whatever is run from the cron lacks the "usual" environment variables setup, namely, PATH is what you're missing the most:

def roda_processo(processo):
    os.system('/usr/local/bin/python3.7 {}'.format(processo))
