Hey, I have seen that one person before me had the same error. I want to know if there’s a way to solve this. I tried doing it on my own, and I got this error afterward I followed the exact instructions given in the textbook and got the same error. I have tried several times to follow ll the instructions to not avail.

What should I do?

Hi @20Sianjave04, welcome to the community!

The error you are sharing is saying your program cannot find the package exercise_33.

  • Is it a package in your workspace?
  • Does the package contain a msg directory with the message you are trying to use?
  • Has the package been built and the workspace built before running your program?

A good way to check if your package is properly built is using roscd [package_name]. If it takes you to the package path, then it is built correctly.
