大概几天没有运行ROS了,今天运行一下出现以下错误,在此记录一下
zztsj@tsj:~$ roscore ... logging to /home/zztsj/.ros/log/3455db8a-1536-11eb-9296-9822efa1466f/roslaunch-tsj-8025.log Checking log directory for disk usage. This may take a while. Press Ctrl-C to interrupt Done checking log file disk usage. Usage is <1GB. RLException: Unable to contact my own server at [http://tsj:40035/]. This usually means that the network is not configured properly. A common cause is that the machine cannot ping itself. Please check for errors by running: ping tsj For more tips, please see http://wiki.ros.org/ROS/NetworkSetup The traceback for the exception was written to the log file
解决方法如下:
进入到配置文件
vim ~/.bashrc
加入以下两段代码
1 export ROS_HOSTNAME=localhost 2 export ROS_MASTER_URI=http://localhost:11311
更新环境变量
source ~/.bashrc
就顺利解决了,再次启动就可以正常的跑起来了。
