ROS项目中mini-httpd出现这个错误的原因是什么？

Question

错误：

[mini_httpd-2] 进程已经死亡 [pid 6395, exit code 127, cmd /home/santiago/catkin_ws/src/map_nav_manager/scripts/mini-httpd.sh __name:=mini_httpd __log:=/home/santiago/.ros/log/53d109f0-aaae-11ea-83ba-7085c2b46229/mini_httpd-2.log]。 日志文件： /home/santiago/.ros/log/53d109f0-aaae-11ea-83ba-7085c2b46229/mini_httpd-2*.log

mini-httpd.sh 中的代码：

#!/bin/sh 

# Run the mini-httpd webserver on the port defined in the
# mini-httpd.conf file and set the document directory to the current
# directory

PID=`pidof mini-httpd`

if [ ! -z $PID ]; then
    kill $PID
fi

sleep 1

echo "Launching mini-httpd..."

/usr/sbin/mini-httpd -C `rospack find map_nav_manager`/scripts/mini-httpd.conf -d `rospack find map_nav_manager`

mini-httpd.conf 中的代码：

# Example config for mini_httpd.

有谁知道可能是什么错误？

日志是怎么说的？

也许用户nobody没有读取或访问/home/santiago/catkin_ws/src/map_nav_manager/./web/的权限。
