Some problems

[AndyLin31]

1. django.conf.urls.url() was deprecated in Django 3.0, and is removed in Django 4.0+. url(r'^start$', respond.default), should be changed to re_path(r'^start$', respond.default) in .\server\server\urls.py
2. fcntl is not supported on Windows, but you can add fcntl.py in Lib folder:

def fcntl(fd, op, arg=0):
return 0

def ioctl(fd, op, arg=0, mutable_flag=True):
if mutable_flag:
return 0
else:
return ""

def flock(fd, op):
return

def lockf(fd, operation, length=0, start=0, whence=0):
return
