flask mongoengine from mongoengine.dococument导入document，Embe

Question

我想使用flask mongoengine开发应用程序，但在启动应用程序时出现importError

我的烧瓶运行.py

#!/usr/bin/env python
# -*- coding: utf-8 -*-
from app import app
if __name__ == '__main__':
app.run(debug=True)

我的应用程序init.py

#!/usr/bin/env python
# -*- coding: utf-8 -*-
from flask import Flask
import flask_mongoengine
from flask_mongoengine import MongoEngine
app = Flask(__name__)
app.config['MONGODB_SETTINGS'] = {
'db':   'datasync_datax',
'host': '192.168.100.85',
'port': 27017
}
db = MongoEngine()
db.init_app(app)

启动时遇到的问题：

我在python2.7中的开发环境

我更新了我的图书馆烧瓶mongoengine！

sudo pip install --upgrade flask-mongoengine
