Ubuntu 16中的SystemD python任务

我正试图在Ubuntu16中使用systemd执行python3。 以下是配置

[Unit]
Description=email notification server
After=multi-user.target

[Service]
WorkingDirectory=/home/ubuntu/email-noti
Restart=on-failure
ExecStart=/usr/lib/python3 /home/ubuntu/email-noti/email_reader.py 

[Install]
WantedBy=multi-user.target

*请注意，

email\u reader.py

从

/home/ubuntu/email noti/

但它总是以以下错误结束

● email-noti.service - email notification server
   Loaded: loaded (/etc/systemd/system/email-noti.service; enabled; vendor preset: enabled)
   Active: inactive (dead) (Result: exit-code) since Tue 2017-03-07 18:00:38 UTC; 6s ago
  Process: 11859 ExecStart=/usr/lib/python3 /home/ubuntu/email-noti/email_reader.py (code=exited, status=203/EXEC)
 Main PID: 11859 (code=exited, status=203/EXEC)

Mar 07 18:00:38 ip-172-31-24-115 systemd[1]: Stopped email notification server.

Mar 07 18:00:38 ip-172-31-24-115 systemd[1]: Failed to start email notification server.

但是，当我手动执行

email\u reader.py

时，它完全可以正常工作

感谢任何帮助

只是好奇，一旦我们设置了WorkingDirectory，它就可以导入WorkingDirectory中的所有.py文件和.json文件了？您正在询问systemd常见问题解答的变体。奇怪的是，一旦我们设置了WorkingDirectory，它就可以导入WorkingDirectory中的所有.py文件和.json文件了？你问的是systemd FAQ的一个变体。
