PythonAnywhere WSGI Typeerror：__ call __（）只需要2个参数（给定3个）

Question

最近，我正试图从https://github.com/arvoelke/Dixit为学校节日制作Dixit在线服务器，但我遇到了一个问题。当我在我自己的Pythonanywhere web选项卡上重新加载我的Web应用程序时，错误日志显示，

  

'Typeerror：调用（）只需要2个参数（3个给定）'。

我试图在每个Dixit代码中找到'调用（）'函数的位置，但我找不到它。我该怎么办？

这是一个与WSGI相关的代码，这个代码是'server.py'。

class Application(tornado.web.Application):
"""Main application class for holding all state."""

def __init__(self, *args, **kwargs):
    """Initializes the users, games, chat log, and cards."""
    self.users = Users()
    self.games = []
    self.chat_log = ChatLog()

    # Specifies where to find all the card images for each set.
    self.card_sets = [CardSet(name, find_cards(folder), enabled)
        for name, (folder, enabled) in kwargs['card_sets'].iteritems()]
    self.admin_password = kwargs['admin_password']

    super(Application, self).__init__(*args, **kwargs)

settings = {
    'static_path' : os.path.join(os.path.dirname(__file__), 'static'),
    'template_path' : os.path.join(os.path.dirname(__file__), 'templates'),
    'debug' : True
}

configFilename = (sys.argv + ['config.json'])[1]
settings.update(config.parse(os.path.join(os.path.dirname(__file__), 
configFilename)))

application = Application([
(r'/', MainHandler),
(r'/admin', AdminHandler),
(r'/main.js', MainJSHandler),
(r'/main.css', MainCSSHandler),
(r'/setusername', SetUsernameHandler),
(r'/create', CreateHandler),
(r'/getgames', GetGamesHandler),
(r'/getusers', GetUsersHandler),
(r'/game/([0-9]+)/(.+)', GameHandler),
(r'/chat', ChatHandler),
], **settings)

if __name__ == "__main__":

    application.listen(settings['port'])
    tornado.ioloop.IOLoop.instance().start()

这个是'jangheunghsstudentserver_pythonanywhere_com_wsgi.py'。

import tornado.web
import tornado.wsgi

def application(environ, start_response):
    if environ.get('PATH_INFO') == '/':
        status = '200 OK'
        # content = HELLO_WORLD
    else:
        status = '404 NOT FOUND'
        content = 'Page not found.'
    response_headers = [('Content-Type', 'text/html'), ('Content-Length', str(len(content)))]
    start_response(status, response_headers)
    yield content.encode('utf8')

import sys

path = '/home/JangheungHSStudentServer/DixitOnline'
if path not in sys.path:
    sys.path.append(path)
from server import application

请注意。我不使用任何python web框架，如django，flask。
