ImportError:没有名为flask.ext.restless的模块

我正在尝试为sqlalchemy数据库创建Restful端点。但由于某种原因,它无法找到Flask Restless扩展。

当我运行该文件时,我收到此错误:

Traceback (most recent call last):
  File "./rest1.py", line 7, in <module>
    import flask.ext.restless
  File "/home/ian/git_dev/flask_rest/test2/flask/local/lib/python2.7/site-packages/flask/exthook.py", line 86, in load_module
    raise ImportError('No module named %s' % fullname)
ImportError: No module named flask.ext.restless

我安装了Flask,Flask-Restless和SQLalchemy,但它仍然无效。

Django==1.6.5
Flask==0.10.1
Flask-Restless==0.13.1
Jinja2==2.7.2
MarkupSafe==0.23
PAM==0.4.2
Pillow==2.3.0
SQLAlchemy==0.9.4

这是我的代码:

#!flask/bin/python
#!/usr/bin/python
# -*- mode: python -*-

from flask import Flask
from sqlalchemy import Column, Date, DateTime, Float, Integer, Unicode
from sqlalchemy import create_engine
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy.orm import scoped_session, sessionmaker
import flask.ext.restless

app = Flask(__name__)
engine = create_engine('sqlite:////tmp/testdb.sqlite', convert_unicode=True)
Session = sessionmaker(autocommit=False, autoflush=False, bind=engine)
mysession = scoped_session(Session)

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

class Test_Table(Base):
    __tablename__ = 'plot'
    id = Column(DateTime, primary_key=True)
    value = Column(Integer)
    type = Column(Unicode)
    max = Column(Integer)
    min = Column(Integer)


Base.metadata.create_all()

manager = flask.ext.restless.APIManager(app, flask_sqlalchemy_db=db)

manager.create_api(Test_Table, methods=['GET', 'POST', 'PUT' 'DELETE'])

app.run()

我在虚拟环境内外都尝试过Flask-Restful。但我仍然得到同样的结果。

您可以尝试重新安装pip install --upgrade --force-reinstall flask_restless

如果不起作用:

github安装flask_restless 0.14-dev

git clone https://github.com/jfinkels/flask-restless

 cd flask-restless
 pip install -r requirements-doc.txt

使用import flask_restless

   flask_restless.__version__
   '0.13.1'

确保python正在查看flask_restless.

的正确版本

你的道路上似乎也有一个“烧瓶”目录:

'/home/ian/git_dev/flask_rest/test2/flask/local/lib/python2.7/site-packages/flask/exthook.py'

可能与您的导入产生冲突。

您可以直接从Github安装最新的flask-restless:

pip install git+https://github.com/jfinkels/flask-restless.git

像往常一样,在安装之前,如果您正在使用像virtualenv这样的东西,请确保您处于正确的环境中
