#我的源代码是Hello.py,就是4-3节视频讲的那个程序

# -*- coding: utf-8 -*-
from flask import Flask

app = Flask(__name__)

@app.route('/')
def hello_world():
   return 'Hello World'

if __name__ =='__main__':

  这个问题以前在群里提过的
  
  加入debug  就会报错，解决方案：
  pip uninstall werkzeug  && pip install werkzeug==0.14.1

  我在windows端Pycharm的终端上运行开启debug可以正常运行，在虚拟机上的centos上就不能开启debug，该装的环境我都对着视频装了

  老师，你常用的联系方式是什么，我想私信你，我打算用这个项目做本科的毕业设计，所以时间比较紧，麻烦你及时解答我的问题，谢谢啦，我这个bug都已经调一天了，各种百度，实在是不知道怎么回事
