1. The path setting of the ROS working space fails when the boot starts
Symptom: In Tutorial: section 5.1 of Http://wiki.ros.org/cn/ROS/Tutorials/CreatingPackage, the following command failed to run:
Hint error:[rospack] error:package ' beginner_tutorials ' not found
Cause: The root path of the Catkin workspace was not found because it failed to create the source of the Catkin. This is due to a failure in setting the workspace source in section 4 to fail with the following command:
Http://wiki.ros.org/cn/ROS/Tutorials/InstallingandConfiguringROSEnvironment
$ source Devel/setup.bash
Do not know what reason, can only move to make changes.
Workaround :
Ubuntu under situation processing
$ cd ~
$gedit. BASHRC
Add two more lines to the back.
Source/opt/ros/indigo/setup.bash
Source/home/horsetail/catkin_ws/devel/setup.bash
