两天了毫无进展，我不知道该怎么办...

答案1

在这种情况下，您实际上根本不需要 sudo，因为您的服务是系统范围的服务（位于 /lib/systemd/system 中），因此默认情况下它将以 root 身份运行。您只需/home/Butter_Manager/sudo从服务文件中删除零件即可。

以下是您的服务失败的原因：

/home/Butter_Manager/sudo: No such file or directory

这个意思/home/Butter_Manager/sudo是不存在的。最有可能的sudo是/usr/bin/sudo或/bin/sudo。您可以通过运行找到它的路径which sudo。运行realpath sudo将简单地返回您当前的工作目录 + sudo（请参阅man realpath）。我思考你的命令的第二部分也有这个问题。我思考你的意思是/bin/env /bin/python3.8而不是/home/Butter_Manager/env/bin/python3.8。
