无法将 Google Cloud Print 作为守护进程运行

Question

我在安装Google Cloudprint的Python脚本时遇到了一些问题。

holmen@filserver:~/tmp$ sudo service cloudprint start
Starting Google Cloud Print: daemon module required for -d
        yum install python-daemon, or apt-get install python-daemon, or pip install python-daemon
holmen@filserver:~/tmp$ sudo apt-get install python-daemon
Reading package lists... Done

python-daemon is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

虽然我已经安装了python-daemon，但还是出现了错误。

我的init-d脚本是这样的：

#!/bin/bash
# /etc/rc.d/cloudprint
# Description: Starts the Google Cloud Print script on startup
# ----------------
#
### BEGIN INIT INFO
# Provides: Cloud-Print
# Required-Start: $cups $network $local_fs $syslog
# Required-Stop: $local_fs $syslog
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Description: Start Google Cloud Print
### END INIT INFO

USER="holmen"
PIDFILE="/var/run/cloudprint/pid"

case $1 in
        start)
                echo -n "Starting Google Cloud Print: "
                sudo -u $USER cloudprint -d -p $PIDFILE
        ;;
        stop)
                echo -n "Stopping Google Cloud Print: "
                killall cloudprint
        ;;
        restart)
                echo -n "Restarting Google Cloud Print: "
                killall cloudprint
                sudo -u $USER cloudprint -d -p $PIDFILE
        ;;
        *)
                echo "Usage: cloudprint {start|stop|restart}"
        ;;

我也遇到过同样的问题，后来通过卸载守护进程模块，然后安装python-daemon这个包解决了。也就是说，在我的Debian系统上：

pip uninstall daemon
apt-get install python-daemon
