One of the most common issues that appear on this forum is when ROS can’t find a certain package. The error message shows:
package ‘$PACKAGE_NAME’ not found
One of the first things to know is that this can happen when the workspace doesn’t compile correctly. This can be often quickly solved by deleting the
devel/ folders and compiling again:
cd ~/catkin_ws/ rm -rf build/ devel/ catkin_make
Also, don’t forget to run
If this doesn’t fix the problem, then I recommend going through the necessary additions in
package.xml when a new package is created. You can find these instructions in the first unit of our course ROS Basics in 5 Days.
