我有這個劇本時，我從它工作正常運行命令行比...Python的crontab的嘗試，除了ValueError異常

但是當我嘗試在crontab來安排我得到的波紋錯誤
# Edit this file to introduce tasks to be run by cron.
#
# Each task to run has to be defined through a single line
# indicating with different fields when the task will be run
# and what command to run for the task
#
# To define the time you can provide concrete values for
# minute (m), hour (h), day of month (dom), month (mon),
# and day of week (dow) or use '*' in these fields (for 'any').#
# Notice that tasks will be started based on the cron's system
# daemon's notion of time and timezones.
#
# Output of the crontab jobs (including errors) is sent through
# email to the user the crontab file belongs to (unless redirected).
#
# For example, you can run a backup of all your user accounts
# at 5 a.m every week with:
# 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/
#
# For more information see the manual pages of crontab(5) and cron(8)
#
# m h dom mon dow command
#SENSE

我得到這個錯誤：
Traceback (most recent call last): File "...", line 239, in (error_code, error_message) = e ValueError: need more than 1 value to unpack
我認爲它做還有的「克洛諾斯時間表執行祚之間沒有管道b「和它自己的腳本，我不知道這是否有任何意義，就像它不知道從哪裏獲得信息和反之亦然......
實質上，在試圖捕獲EXECUT的異常MSSQL JOB命令。
只是代表用'print（e）'來表示該行的錯誤。這可能是你不期待的事情。一旦你修復了這個錯誤，你應該把'except Exception ...'改成''WhateverYouExpect ...'，這樣未知的錯誤就不會默默地通過。 – zondo
