Question

我有一个有效的python3脚本，我已经通过crontab -e设置了crontab。我添加了这一行

* * * * *  /Library/Frameworks/Python.framework/Versions/3.6/bin/python3 /Users/harvey/PycharmProjects/3_5_pgm/3woerter.py

cron正在执行脚本，但我收到一封包含此错误消息的电子邮件：

X-Cron-Env: <SHELL=/bin/sh>
X-Cron-Env: <PATH=/usr/bin:/bin>
X-Cron-Env: <LOGNAME=harvey>
X-Cron-Env: <USER=harvey>

UnicodeEncodeError: 'ascii' codec can't encode character '\xf6' in position 121: ordinal not in range(128)

所以我认为cron使用python2而不是python3 当我通过终端直接尝试命令时，一切正常。

我怎样才能确保cron正在使用python3？

我也碰到了这个！我通过添加LC_ALL和LANG解决了这个问题： LC_ALL=en_US.UTF-8 LANG=en_US.utf-8 * * * * * /Library/Frameworks/Python.framework/Versions/3.6/bin/python3 /Users/harvey/PycharmProjects/3_5_pgm/3woerter.py

我之前学到了如何阅读http://click.pocoo.org/5/python3/#python-3-surrogate-handling以解决另一个问题
