今天我把自己的电脑命令提示符等改了,现在运行roscore报错:
... logging to /home/w/.ros/log/481d4d36-f716-11e9-9b7a-4cedfb3da8b4/roslaunch-w-23661.log Checking log directory for disk usage. This may take awhile. Press Ctrl-C to interrupt Done checking log file disk usage. Usage is <1GB. Unable to contact my own server at [http://w:46221/]. 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 w For more tips, please see http://www.ros.org/wiki/ROS/NetworkSetup The traceback for the exception was written to the log file
然后我试着ping了一下自己:
ping: unknown host w
解决办法:
首先查看自己的IP:10.10.10.XXX
ifconfig
enp6s0 Link encap:以太网 硬件地址 4c:ed:fb:3d:a8:b4
inet 地址:10.10.10.XXX 广播:10.10.10.255 掩码:255.255.255.0

碰撞:0 发送队列长度:1000
接收字节:166128186 (166.1 MB) 发送字节:166128186 (166.1 MB)
然后设置ros_ip
export ROS_IP="xxx.xxx.xxx.xxx"
现在再运行roscore就OK了.
roscore报错:Unable to contact my own server at [http://w:46221/].
