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run.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：

ImportError: cannot import name Document

我在python2.7中的开发环境

我不知道怎么了。

pymongo，mongoengine，flask-mongoengine已安装

问题已经解决。

我更新了我的flask-mongoengine库！

sudo pip install --upgrade flask-mongoengine

mongoengine.document导入文档中的flask-mongoengine，EmbeddedDocument ImportError：无法导入名称Document
