Python：ImportError：无法导入名为的模块

Question

i'm working with python 3.7 and I try to develop an ecommerce api with flask and many other flask extension but when i want to initiate for example my migration to create databse i got an import error I have a such great problem with import in python我总是对此感到沮丧，有人能说出我做错了什么吗？ 我把我的根目录的架构和 factory.py 文件放在我试图导入一些变量的地方

我把当我尝试运行python shared/manage.py时得到的堆栈跟踪放在下面

Traceback (most recent call last):
  File "shared/manage.py", line 1, in <module>
    from factory import create_app
ImportError: No module named factory

我这是我的 factory.py 文件

from flask import Flask
from flask_sqlalchemy import SQLAlchemy
from flask_mail import Mail
from config import Config
from flask_bcrypt import Bcrypt
from flask_cors import CORS
from flask_migrate import Migrate
import os
db = SQLAlchemy()
mail = Mail()
bcrypt = Bcrypt()
cors = CORS()
migrate = Migrate()


def create_app():
    app = Flask(__name__, root_path=os.getcwd())
    app.config.from_object(Config)

    db.init_app(app)
    mail.init_app(app)
    cors.init_app(app)
    migrate.init_app(app, db)

    from admin.views import admin
    from users.views import users
    from orders.views import order
    from products.views import product
    from main.views import main
    from adresses.views import adresse
    from comments.views import comment
    from car.views import carmanager
    from categories.views import category
    from quote.views import quote
    from message.views import message
    from wishlist.views import wishlist

    with app.app_context():
        app.register_blueprint(admin)
        app.register_blueprint(order)
        app.register_blueprint(users)
        app.register_blueprint(product)
        app.register_blueprint(main)
        app.register_blueprint(adresse)
        app.register_blueprint(comment)
        app.register_blueprint(carmanager)
        app.register_blueprint(category)
        app.register_blueprint(quote)
        app.register_blueprint(message)
        app.register_blueprint(wishlist)

    return app

如果有人可以提供帮助，那将非常有帮助

问题不在于factory.py 。 您正在尝试在目录树中导入更高一级的文件。 因此，您的导入语句应该是：

from ..factory import create_app
