TypeError: __init__() got an unexpected keyword argument 'method' 类型错误：__init__()收到了一个意外的关键字参数'method'。

我正在编写一个Flask项目，但是当我尝试运行python manage.py时，跟踪信息告诉我：

Traceback (most recent call last):
  File "manage.py", line 5, in 
    from app import db,create_app
  File "/home/humbert/2017-sharing-backend/sharing/app/__init__.py", line 42, in 
    app.register_blueprint(main_blueprint, url_prefix='/main')
  File "/home/humbert/venv/local/lib/python2.7/site-packages/flask/app.py", line 64, in wrapper_func
    return f(self, *args, **kwargs)
  File "/home/humbert/venv/local/lib/python2.7/site-packages/flask/app.py", line 951, in register_blueprint
    blueprint.register(self, options, first_registration)
  File "/home/humbert/venv/local/lib/python2.7/site-packages/flask/blueprints.py", line 154, in register
    deferred(state)
  File "/home/humbert/venv/local/lib/python2.7/site-packages/flask/blueprints.py", line 173, in 
    s.add_url_rule(rule, endpoint, view_func, **options))
  File "/home/humbert/venv/local/lib/python2.7/site-packages/flask/blueprints.py", line 76, in add_url_rule
    view_func, defaults=defaults, **options)
  File "/home/humbert/venv/local/lib/python2.7/site-packages/flask/app.py", line 64, in wrapper_func
    return f(self, *args, **kwargs)
  File "/home/humbert/venv/local/lib/python2.7/site-packages/flask/app.py", line 1043, in add_url_rule
    rule = self.url_rule_class(rule, methods=methods, **options)
TypeError: __init__() got an unexpected keyword argument 'method'

我认为我的manage.py是正确的，但是我无法找出错误。

__init__.py中的错误部分是：

from .main import main as main_blueprint
app.register_blueprint(main_blueprint, url_prefix='/main')
from .auth import auth as auth_blueprint
app.register_blueprint(auth_blueprint, url_prefix="/auth")
from . import views

我真的需要一些帮助，谢谢！
