He estado trabajando en una aplicación Flask durante algunas semanas. Lo terminé hoy y fui a implementarlo... y ahora no se inicia.

No agregué ni eliminé ningún código, así que suponga que algo cambió en el proceso de implementación.

De todos modos, aquí está el error completo que se muestra en la terminal:

 Traceback (most recent call last): File "C:\Users\Kev\Documents\Projects\Docket\manage.py", line 5, in <module> from app import create_app, db File "C:\Users\Kev\Documents\Projects\Docket\app\__init__.py", line 21, in <module> from app.api import api, blueprint, limiter File "C:\Users\Kev\Documents\Projects\Docket\app\api\__init__.py", line 2, in <module> from flask_restplus import Api File "C:\Users\Kev\.virtualenvs\Docket-LasDxOWU\lib\site-packages\flask_restplus\__init_ _.py", line 4, in <module> from . import fields, reqparse, apidoc, inputs, cors File "C:\Users\Kev\.virtualenvs\Docket-LasDxOWU\lib\site-packages\flask_restplus\fields. py", line 17, in <module> from werkzeug import cached_property ImportError: cannot import name 'cached_property' from 'werkzeug' (C:\Users\Kev\.virtualen vs\Docket-LasDxOWU\lib\site-packages\werkzeug\__init__.py)

También aquí está el código en los tres archivos mencionados.

manage.py :

 from apscheduler.schedulers.background import BackgroundScheduler from flask_script import Manager from flask_migrate import Migrate, MigrateCommand from app import create_app, db app = create_app() app.app_context().push() manager = Manager(app) migrate = Migrate(app, db) manager.add_command('db', MigrateCommand) from app.routes import * from app.models import * def clear_data(): with app.app_context(): db.session.query(User).delete() db.session.query(Todo).delete() db.session.commit() print("Deleted table rows!") @manager.command def run(): scheduler = BackgroundScheduler() scheduler.add_job(clear_data, trigger='interval', minutes=15) scheduler.start() app.run(debug=True) if __name__ == '__main__': clear_data() manager.run()

app/__init__.py :

 from flask import Flask from flask_sqlalchemy import SQLAlchemy from flask_login import LoginManager from config import Config db = SQLAlchemy() login = LoginManager() def create_app(): app = Flask(__name__) app.config.from_object(Config) db.init_app(app) login.init_app(app) login.login_view = 'login' from app.api import api, blueprint, limiter from app.api.endpoints import users, todos, register from app.api.endpoints.todos import TodosNS from app.api.endpoints.users import UserNS from app.api.endpoints.register import RegisterNS api.init_app(app) app.register_blueprint(blueprint) limiter.init_app(app) api.add_namespace(TodosNS) api.add_namespace(UserNS) api.add_namespace(RegisterNS) return app

api/__init__.py :

 from logging import StreamHandler from flask_restplus import Api from flask import Blueprint from flask_limiter import Limiter from flask_limiter.util import get_remote_address blueprint = Blueprint('api', __name__, url_prefix='/api') limiter = Limiter(key_func=get_remote_address) limiter.logger.addHandler(StreamHandler()) api = Api(blueprint, doc='/documentation', version='1.0', title='Docket API', description='API for Docket. Create users and todo items through a REST API.\n' 'First of all, begin by registering a new user via the registration form in the web interface.\n' 'Or via a `POST` request to the `/Register/` end point', decorators=[limiter.limit("50/day", error_message="API request limit has been reached (50 per day)")])

Intenté reinstalar el flask y flask_restplus pero no tuve suerte.
