I have a problem, I can´t run any .launch, in all cases the error is:
(Yesterday I could do it)
[topics_quiz.launch] is neither a launch file in package [topics_quiz] nor is [topics_quiz] a launch file name
The traceback for the exception was written to the log file
Welcome to the Community!
To help you better, could you please share a screenshot showing the command you ran and the error output?
Are you having problems with only this package or every package? Could you please try the following?
Also keep in mind, that the name of the package is not defined by your folder name, but by the name defined in the CMakeLists.txt and package.xml. This can be a common mistake when copying those files from a different package. It’s always best to use
And then to only copy paste specific lines from another package, such as dependencies.
