Question

所以我写了一个漂亮的自动化脚本，通过jira模块+方便的花花公子逻辑为我完成了一些工作。它通过命令行完美运行：

me@local] ~/Documents/auto_updater > python /Users/me/Documents/auto_updater/jira_updater.py 
Missing info starting
  checking out:  ES-20157
    No array outage
    Already has sev1_missing_outage label.
***snip***

在没有python调用的情况下，它也可以很好地运行fullpath：

me@local] ~/Documents/auto_updater > /Users/me/Documents/auto_updater/jira_updater.py 
Missing info starting
  checking out:  ES-20157
    No array outage
    Already has sev1_missing_outage label.

现在 - 假设它正常工作意味着生活是美好的，我决定将它设置在crontab上30分钟，并且我每次都无法找到jira模块时遇到垃圾邮件失败：< / p>

Traceback (most recent call last):
  File "/Users/me/Documents/auto_updater/jira_updater.py", line 3, in <module>
    from jira.client import JIRA
ImportError: No module named jira.client

最初我遇到＃！/ usr / bin / python路径的问题，所以我把它切换到＃！/ usr / bin / env python：

[me@local] ~/Documents/auto_updater > head jira_updater.py 
#!/usr/bin/env python

from jira.client import JIRA
import random

# Here's some responses that we can randomize from so it doesn't feel quite so botty.
FIRST_RESPONSES = ['- Do you need help moving this forward?',
                  '- Can I help you get traction on this?',

我已经看到一些变通方法声明我只需要我的cronjob以明确声明的python路径运行，但这似乎是一个伪劣的解决方法，我已经设置了一个服务器为我运行这个，所以我' d喜欢通过使事情正常工作来解决它 - 但我无法弄清楚为什么cronjob run命令似乎无法找到模块，但我可以以root身份运行它，其语法与crontab中指定的相同。我通过手动运行crontab中指定的相同commant来验证这一点：

me@local] ~/Documents/auto_updater > crontab -l
*/30 * * * * python /Users/me/Documents/auto_updater/jira_updater.py >> /Users/me/Documents/auto_updater/updated_log.txt

任何人都知道为什么cronjob找不到模块，或者手动指定pythonpath真的是唯一的“修复”？

可能会在jira_updater.py中明确地附加jira的lib路径。

# added code below before import jira
# append path where jira lib located, for example in /usr/bin/lib
import sys
sys.path.append('/usr/bin/lib')

# if yout don't know where jira located, use code below to get jira path first
# then put the path found into code sys.path.append above
import imp;imp.find_module('jira')

仅针对crontab作业的ImportError？
