Elixir: module Platform.Parsing.Behaviour is not loaded and could not be found

Question

I try to fix the compiler error:

** (CompileError) main.exs:2: module Platform.Parsing.Behaviour is not loaded and could not be found (elixir 1.12.2) expanding macro: Kernel.use/1 main.exs:2: Parser (module)

Do you have an idea to fix that?
Thanks in advance :)!

I don't have any idea, how to fix that.
