在 virtualenv 中将 Python 脚本作为服务运行

Question

我想运行一个 python 脚本，它使用 virtualenv 作为服务。我已经研究了一些，但找不到可行的解决方案。我已将虚拟环境 python 的路径放在 python 的第一行。该服务如下所示：

[Unit]
Description=Telegram Bot Service
After=multi-user.target
[email protected]

[Service]
Type=simple
ExecStart=/usr/bin/python3.7 /home/pi/github/python/telegrambot.py
StandardInput=tty-force

[Install]
WantedBy=multi-user.target

错误：
