Sqlalchemy 无法导入烧瓶

所以我试着用烧瓶不安。很遗憾，我无法导入flask.ext.untivent

>>> from flask.ext.restless import APIManager
Traceback (most recent call last):

我一直在尝试做这个教程（虽然有点修改）： 作者=“凯瑟先生”

import flask
from sqlalchemy import Column, Integer, String, Sequence
from sqlalchemy import ForeignKey
from sqlalchemy import create_engine
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy.orm import backref, relationship
from sqlalchemy.orm import scoped_session, sessionmaker
from flask.ext.restless import APIManager

app = Flask(__name__)
engine = create_engine('mysql+mysqlconnector://flask:dummypass@localhost/test', convert_unicode=True)
Session = sessionmaker(autocommit=False, autoflush=False, bind=engine)
mysession = scoped_session(Session)

Base = declarative_base()
Base.metadata.bind = engine


class Person(Base):
    __tablename__ = 'people'

    id = Column(Integer, Sequence('person_id_seq'), primary_key=True)
    first_name = Column(String(50))
    last_name = Column(String(50))
    url = Column(String(150))
    about = Column(String(400))

    def __repr__(self):
    return "Person<first_name=%s,last_name=%s,url=%s" % (self.    first_name, self.last_name, self.url)


# Create the database tables.
Base.metadata.create_all()

# Create the Flask-Restless API manager.
manager = flask.ext.restless.APIManager(app, session=mysession)

# Create API endpoints, which will be available at /api/<tablename> by
# default. Allowed HTTP methods can be specified as well.
manager.create_api(Person, methods=['GET'])


# start the flask loop
app.run()

导入烧瓶
从sqlalchemy导入列、整数、字符串、序列
从sqlalchemy导入外键
从sqlalchemy导入创建引擎
从sqlalchemy.ext.declarative导入声明性基础
从sqlalchemy.orm导入backref，关系
从sqlalchemy.orm导入作用域的_会话，sessionmaker
来自flask.ext.untivent导入管理器
app=烧瓶（名称）
引擎=创建引擎（'mysql+mysqlconnector://flask:dummypass@localhost/test'，convert_unicode=True）
Session=sessionmaker（autocommit=False，autoflush=False，bind=engine）
mysession=作用域_会话（会话）
Base=声明性_Base（）
Base.metadata.bind=引擎
班级人员（基本）：
__tablename_uuu='people'
id=列（整数，序列（'person\u id\u seq'），主键=True）
第一个名称=列（字符串（50））
姓氏=列（字符串（50））
url=列（字符串（150））
关于=列（字符串（400））
定义报告（自我）：
return“Person对于那些在Python3中与flask Untivent有相同问题的人，升级到。问题已经解决

似乎根据Flask Untivent docs python 3（我正在使用的）在0.13之前不受支持（在dev分支上）
