UBUNTU将新路径添加到ROS_PACKAGE_PATH中。

first,查看路径

chen@chen-HP:~$ echo $ROS_PACKAGE_PATH

/opt/ros/indigo/share:/opt/ros/indigo/stacks

添加

chen@chen-HP:~$ echo "export ROS_PACKAGE_PATH=~/dev/rosbook:${ROS_PACKAGE_PATH}">>~/.bashrc
chen@chen-HP:~$ . ~/.bashrc

最后查看环境变量：env

可以看到多了ROS_PATHAGE_PATH的路径多了一个分号。
