AttributeError：“模块”对象在Django项目中没有属性“ META”

Question

I am working on a blog in Python-Django. When I run the command "python manage.py runserver" in my project folder, I get following error:

Traceback (most recent call last):
  File "manage.py", line 6, in <module>
    server = request.META.get('wsgi.file_wrapper', None)
AttributeError: 'module' object has no attribute 'META'

I have not seen this error anywhere. Should I include Meta class in my installed_apps? How do I do it?

Here is my manage.py:

#!/usr/bin/env python
import os
import sys
from django.http import request

server = request.META.get('wsgi.file_wrapper', None)
if server is not None and server.__module__ == 'django.core.servers.basehttp':
    print('inside dev')

if __name__ == "__main__":
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "dj1.settings")

    from django.core.management import execute_from_command_line

    execute_from_command_line(sys.argv)

and settings.py:

This is really a big code bulder.

This piece of code here makes no sense inside the manage.py

from django.http import request

server = request.META.get('wsgi.file_wrapper', None)
if server is not None and server.__module__ == 'django.core.servers.basehttp':
    print('inside dev')

Perhaps you copied it from somewhere, and didn't put it where it belongs.

This piece of coude would belong in a view. It will never work inside manage.py, and makes asolutely no sense there.

[EDIT] ALSO, in a view, you should NOT include the import, or you'll get the same error. That means, don't include this from django.http import request
