1、NotImplementedError

import tornado.ioloop
import tornado.web
import tornado.httpserver

class MainHandler(tornado.web.RequestHandler):
    def get(self):
        self.write("Hello, Nowamagic")


application = tornado.web.Application([(r"/", MainHandler)])
# httpServer = tornado.httpserver.HTTPServer(application)

找到tornado/platform/asyncio.py 文件
在文件裏面加上

import sys
if sys.platform == 'win32':
    asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy())
