单元x.service未正确加载:参数无效

Question

我试着使用systemd让我的Discord机器人在我的VPS上运行。我使用与我的旧机器人完全相同的设置，但是当我修改ExecStart时，我得到了一个错误

旧设置：

[Unit]
Description=Red-DiscordBotV3
After=multi-user.target
[Service]
WorkingDirectory=/home/laggron/rewrite/lib/python3.6/site-packages/redbot
User=laggron
Group=laggron
ExecStart=/usr/bin/python3.5 /home/username/Red-DiscordBot/red.py --no-prompt
Type=idle
Restart=always
RestartSec=15

[Install]
WantedBy=multi-user.target

新设置：

[Unit]
Description=Red-DiscordBotV3
After=multi-user.target
[Service]
WorkingDirectory=/home/laggron/rewrite/lib/python3.6/site-packages/redbot
User=laggron
Group=laggron
ExecStart=/home/laggron/rewrite/lib/python3.6/ -m redbot Red --dev --no-prompt
Type=idle
Restart=always
RestartSec=15

[Install]
WantedBy=multi-user.target

(新安装使用的是virtualenv，python3.6是从源代码安装的)

我得到的是：

danny_brown5544@ref:/etc/systemd/system $ 
Failed to start redV3.service: Unit redV3.service is not loaded properly: Invalid argument.
See system logs and 'systemctl status redV3.service' for details.

键入systemctl status redV3.service

danny_brown5544@ref:/home/danny_brown5544/Red-DiscordBot $

您的exec start指向一个目录。删除其上的尾随/，并验证这是您在激活virtualenv的情况下使用which python时所需的python的路径
