python - Tornado官方canonical "Hello, world"example app报错怎么解决？

Question

My python version is 2.7.2

python 由 uwsgi 运行 我的 nginx 配置是

location /{

uwsgi_pass 127.0.0.1:8888;

include uwsgi_params;

}

应用.py

import tornado.ioloop
import tornado.web

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

if __name__ == "__main__":
    application = tornado.web.Application([
        (r"/", MainHandler),
    ])
    application.listen(9090)
    tornado.ioloop.IOLoop.instance().start()

然后我运行“我运行“uwsgi -s :9090 -w app”

但它抛出一个错误

[pid: 28719|app: 0|req: 21/21] 118.207.180.64 () {38 vars in 716 bytes} [Sun Mar 23 22:44:34 2014] GET/=> generated 0 bytes in 0毫秒 (HTTP/1.1 500) 0 个字节中的 0 个 header (核心 0 上的 0 个开关)AttributeError:应用程序实例没有调用方法

如何解决？

import tornado.web
import tornado.wsgi
import wsgiref.simple_server

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

if __name__ == "__main__":
    application = tornado.wsgi.WSGIApplication([
        (r"/", MainHandler),
    ])
    server = wsgiref.simple_server.make_server('', 8888, application)
    server.serve_forever()
