roscore啟動不完全問題

 

運行roscore，得到如下日志，且一直卡着無法繼續執行

... logging to /home/xbit/.ros/log/79f2952c-589c-11ea-8213-d0abd5e7d222/roslaunch-x-11085.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.

 

原因：ROS_IP和ROS_HOSTNAME錯誤

解決辦法：將如下腳本加入~/.bashrc中即可

export ROS_HOSTNAME=127.0.0.1 export ROS_IP=127.0.0.1
if [ -f /opt/ros/melodic/setup.bash ]; then
    source /opt/ros/melodic/setup.bash
elif [ -f /opt/ros/kinetic/setup.bash ]; then
    source /opt/ros/kinetic/setup.bash
else
    echo "No ros distro found!"
fi
