python main.py 出错包导入错误

Question

各位好：
我接手一个网站，现在需要测试启动，目前我在虚拟环境中的软件如下（使用pip freeze查看）：

Flask==0.10.1
Flask-Admin==1.0.7
Flask-Auth==0.85
Flask-OAuth==0.12
Flask-SQLAlchemy==1.0
Jinja2==2.7.2
Mako==0.9.1
Markdown==2.4
MarkupSafe==0.19
SQLAlchemy==0.9.4
WTForms==1.0.5
Werkzeug==0.9.4
alembic==0.6.3
argparse==1.2.1
distribute==0.6.24
httplib2==0.8
ipython==1.2.1
itsdangerous==0.24
nose==1.3.0
oauth2==1.5.211
psycopg2==2.5.2
wsgiref==0.1.2

但是，当我处理python main.py的时候，还是会报出如下错误：

homepage)duqi@Lenovo-G480:~/python/homepage$ python main.py
Traceback (most recent call last):
  File "main.py", line 1, in <module>
    from homepage import create_app
  File "/home/duqi/python/homepage/homepage/__init__.py", line 2, in <module>
    from homepage import views
  File "/home/duqi/python/homepage/homepage/views/__init__.py", line 1, in <module>
    from home import blueprint_home
  File "/home/duqi/python/homepage/homepage/views/home.py", line 6, in <module>
    from homepage.helper import render_template, generator_hash
  File "/home/duqi/python/homepage/homepage/helper.py", line 5, in <module>
    from flask_oauth import Oauth
ImportError: cannot import name Oauth

并且，在helper.py的第5行代码是：

from flask_oauth import Oauth

Answer 1

看看人家示例是怎么写的：

from flask_oauth import OAuth

注意检查拼写，少犯这种低级错误。
