Python Raspberry Pi rc.local不执行

我试图在启动时使用rc.local文件在我的Raspberry Pi上执行python温度监控脚本，但在多次尝试后，我都无法让它正常工作。当前我的rc.local如下所示：

#!/bin/sh
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

# Print the IP address
_IP=$(hostname -I) || true
if [ "$_IP" ]; then
  printf "My IP address is %s\n" "$_IP"
fi

# start the temperature monitoring program
python /home/pi/TemperatureMonitoring/TempMonitor.py >> /var/log/rc.local.log 2>&1 &

exit 0

如您所见，我将其设置为将python输出记录到一个文件中，但是在启动期间根本不会创建该文件

检查rc本地服务的状态，我得到以下输出：

pi@raspberrypi:~ $ systemctl status rc-local.service
● rc-local.service - /etc/rc.local Compatibility
   Loaded: loaded (/lib/systemd/system/rc-local.service; static)
  Drop-In: /etc/systemd/system/rc-local.service.d
           └─ttyoutput.conf
   Active: failed (Result: exit-code) since Mon 2017-03-27 12:03:53 CEST; 44s ago
  Process: 565 ExecStart=/etc/rc.local start (code=exited, status=203/EXEC)

Warning: Unit file changed on disk, 'systemctl daemon-reload' recommended.

我已将rc.local文件设置为可执行文件，权限看起来正常：

pi@raspberrypi:~ $ ls -l /etc/rc.local
-rwxr-xr-x 1 root root 549 Mar 27 12:03 /etc/rc.local

此外，当我尝试从终端以root用户身份运行rc.local时，它会正确执行，并创建日志文件（即使打开时它是空的）：

另外，这里是这个输出（我在研究这个问题时看到这个命令，我不确定它是做什么的）：

任何帮助都将不胜感激

编辑：

这是syslog文件引导序列中rc.local似乎失败的部分：

#!/bin/sh in/etc/rc.本地更改为#/bin/bashNothing不幸地发生了变化（相同的203状态码，等等）。你能发布rc.local吗？似乎粘贴到这里太长了，但与我在原始帖子中粘贴的内容相比，我唯一改变的是#！bin/bash，我已经更改了python脚本的名称（我创建了一个非常简单的测试脚本，以确保这不是问题的原因）。
