`flask Db Migrate` Error

We are trying to run a flask db migrate and flask db upgrade which throws the following error: Usage: flask db upgrade [OPTIONS] [REVISION] Error: The file/path provided (C) does

Solution 1:

I think if you are using migrate like you are

migrate.init_app(app, db)  

that you first have to import it and then declare it:

from flask_migrate import Migrate
migrate = Migrate()
migrate.init_app(app, db)

or alternatively I think you could do:

from flask_migrate import Migrate
migrate = Migrate(app, db)
