Files needed for going through exercises aren’t loading( as shown on picture), what should i do ?
Hi Filip,
I found what your problem is. The problem is that you had a package wrong in your catkin_ws
. The wrong package is called exercise23
. That package had a wrong package.xml
file. I found two errors in your package.xml
:
- You removed someway the final tag of the file
</package>
. This was the main cause of the error message you got. Since yourpackage.xml
was wrong, the ROS system was not able to properly find other packages included in theROS_PACKAGE_PATH
. - You did not include
rospy
as a dependency of your package, so you could not compile it.
I corrected those errors for you and recompiled everything in your area. So now you can check your packae.xml
file to see how it should look. Basically I added:
<build_depend>rospy</build_depend>
<build_export_depend>rospy</build_export_depend>
<exec_depend>rospy</exec_depend>
So now you can correctly launch the demo
