Python3 ImportError：无法从“ http”导入名称“ cookies”

这似乎很常见，可能涉及Python 2.x和Python 3.x库之间的冲突。例如，此答案表明问题出在路径上：

导入Python模块失败（http.cookies）

但是我得到的完整错误是：

ImportError: cannot import name 'cookies' from 'http' (/usr/local/lib/python3.7/site-packages/gunicorn/http/__init__.py)

如果我这样做：

cat /usr/local/lib/python3.7/site-packages/gunicorn/http/__init__.py

我懂了：

# -*- coding: utf-8 -
#
# This file is part of gunicorn released under the MIT license.
# See the NOTICE for more information.

from gunicorn.http.message import Message, Request
from gunicorn.http.parser import RequestParser

__all__ = ['Message', 'Request', 'RequestParser']

很明显，对于HTTP我所拥有的版本，没有cookies模块导出。

如果我这样做：

find /usr/local/lib64/python3.7/site-packages/   -name  cookie.py

我看到两个条目：

/usr/local/lib64/python3.7/site-packages/django/contrib/messages/storage/cookie.py

/usr/local/lib64/python3.7/site-packages/django/http/cookie.py

这个文件：

/usr/local/lib64/python3.7/site-packages/django/http/cookie.py

以。。开始：

from http import cookies

http当它存在时，它可以从自身导入http吗？并且http不将其导出到其__init__.py文件中吗？

更新：

如果我运行此命令：

/usr/local/lib/python3.7/site-packages/gunicorn/gunicorn    ecommerce.wsgi:application --bind 0.0.0.0:8000

这是我看到的完整堆栈跟踪：

这是我根据另一个Stackoverflow答案创建的文件：

/usr/local/lib/python3.7/site-packages/gunicorn/gunicorn 

该文件的内容是：

#!/usr/bin/python3

#-*- coding: utf-8 -*-
import re
import sys

from gunicorn.app.wsgiapp import run


if __name__ == '__main__':
        sys.argv[0] = re.sub(r'(-script\.pyw|\.exe)?$','',sys.argv[0])
        sys.exit(run())    

如果我这样做：

find /usr/local/lib/python3.7/   -name cookies.py

我懂了：

/usr/local/lib/python3.7/site-packages/cookies.py
/usr/local/lib/python3.7/site-packages/future/backports/http/cookies.py
/usr/local/lib/python3.7/site-packages/future/moves/http/cookies.py
/usr/local/lib/python3.7/site-packages/requests/cookies.py

如果我打印出sys.path：

for p in sys.path:
    print(p)

我得到：
