为什么 GPSd 客户端不返回数据？

Question

我使用 Neo-M9N 获取纬度、经度、速度等，并将这些值放入 csv 文件中。

我安装了 gpsd python 客户端。我只能使用查看数据

gpsmon /dev/ttyTHS1

但如果我只使用就看不到它

gpsmon

我已经将/etc/default/gpsd文件更改为：

START_DAEMON="true"  
USBAUTO="true" 
DEVICES="/dev/ttyTHS1" 
GPSD_OPTIONS="-n -G" 
GPSD_SOCKET="/var/run/gpsd.sock"

我不知道如何解决这个问题，当我检查状态时，会出现以下内容：

jun 05 17:14:40 jetson-nano-2gb systemd[1]: gpsd.service: Job gpsd.service/start failed with result 'dependency'.
jun 05 17:14:45 jetson-nano-2gb systemd[1]: Dependency failed for GPS (Global Positioning System) Daemon.

Has anyone been able to solve this? Thanks for the help!
