Workspace not properly overlayed by setup script
First day with ROS, trying to configure the environment and following the beginner tutorial here:
http://wiki.ros.org/ROS/Tutorials/Ins...
Everything seemed to be working up until this point, I was able to create the catkin workspace.
$ mkdir -p ~/catkin_ws/src
$ cd ~/catkin_ws
$ catkin_make
These commands work and I was able to create the catkin workspace.
And I don't get an error when I run:
$ source devel/setup.bash
However, now when I run:
$ echo $ROS_PACKAGE_PATH
/home/youruser/catkin_ws/src:/opt/ros/kinetic/share
I get the error:
bash: /home/youruser/catkin_ws/src:/opt/ros/kinetic/share: No such file or directory
If it helps, I am running Linux Ubuntu 16.04 on Oracle VM VirtualBox
Any help with this would be greatly appreciated. Thank you.
