这是 rc.local 文件

python3 /home/sheepify/Desktop/main.py &
exit 0

我在 pi 4 model b 8gb RAM 上使用树莓派操作系统

答案1

确保它位于 /etc/rc.local 的顶部

#!/bin/sh -e

确保 /etc/rc.local 末尾有此内容

exit 0

答案2

rc-local.service: Failed to execute /etc/rc.local: Exec format error

由于没有 shebang 行（#!在 的开头/etc/rc.local），看起来内核已尝试将其作为二进制可执行文件运行，但这显然效果不佳。

与 shell 不同，systemd它不会自动检测没有 shebang 行的脚本：它只是对服务定义行exec()上的任何内容运行系统调用。ExecStart=

如果您绝对想使用rc.local，请将其更改为：

#!/bin/sh -e
python3 /home/sheepify/Desktop/main.py &
exit 0

并确保它被标记为可执行文件 ( sudo chmod a+x /etc/rc.local)。
