Error: No such template 'flask-multidb', cause by Pyinstaller

Questions
When I use the API provided by Flask-Migrate, I successfully implemented database migration in the code. However, when I package it with PyInstaller and run the packaged exe file, this error occurs.

code as follow:

def run_migrations(app, db):
    Migrate(app, db)
    with app.app_context():
        migration_dir = os.path.join(os.getcwd(), 'migrations')
        if not os.path.exists(migration_dir):
            # Regarding the parameter multidb=True being mandatory
            init(directory=migration_dir, multidb=True, template="flask-multidb")
        migrate(directory=migration_dir)
        upgrade(directory=migration_dir)

Hi,

I've never used pyinstaller so just guessing.

The template are not python files, so you may need to tell pyinstaller to include also those files?
