Crontab-Python脚本运行，将输出发送到邮件，但不写入文件

Question

I have a job that I have set to run every 5 minutes. I confirm that it indeed runs by running:

grep CRON /var/log/syslog

It shows that it is running the exact command I need it to run 'python3 /root/foofolder/foo.py R'

Dec 29 23:05:01 fooserver CRON[9306]: (root) CMD (python3 /root/foofolder/foo.py R)

It sends the output to mail. I read the mail and output looks as if I was running it in terminal, exactly as I need. The script is supposed to write out to a file. It fails to do so. Running the script in the command line writes the file just fine. I've given the .py file +x permissions and added

#!/usr/bin/python

to the beginning of the .py script. Is there anything else I am missing?

尝试在脚本的早期（打开文件之前）使用绝对路径和/或os.chdir到一个众所周知的位置。
