Hi, I am currently completing the ROS Basics in 5 days tutorial and I have an issue where the error
“roslaunch: command not found”
is returned when I try example 1.1.
The suggested solution for another user facing this problem was to use “source /opt/ros/noetic/setup.bash” now I get a new message:
“RLException: [move.launch] is neither a launch file in package [publisher_example] nor is [publisher_example] alaunch file name
The traceback for the exception was written to the log file”
I previously completed unit 1 with no errors but I wanted to run through it again after doing some of unit 2, so I am wondering if I broke something while doing so.
Welcome to the Community!
This is strange, could be a temporary problem with that VM. Could you please try again and let us know if you still have the issue?
Usually, I source it as ‘source devel/setup.bash’ from terminal…
Yes, try compiling again and sourcing from
rm -rf build/ devel/
Don’t worry, the system can just source back to your workspace without breaking anything
I have the same problem
Can you close the course and try again? What exactly is your problem? A screenshot or two would be very helpful.
Does that error happen once you close the course and open it again?
yes, I got the error the first time I opened the course and the error still exist even when resetting the course
