What does "no such command" mean when attempting to execute Flask init-db?

edit

"no such command" generally means that the command you are trying to execute is not recognized by the system. In the context of Flask init-db, it could mean that the Flask application you are working with does not have an init-db command or that you are typing the command incorrectly. You may need to double-check your syntax or ensure that you are executing the command in the correct context.
