DeprecationWarning：不建议使用“集合”而不是“ collections.abc”中的ABC或从其中导入ABC，在3.8中它将停止工作

问题描述

我从github下载了一个代码，并试图通过在git bash中运行命令来按原样运行它：python manage.py runserver

但是我遇到此错误：

DeprecationWarning: Using or importing the ABCs from 'collections' instead of from 'collections.abc' is deprecated,and in 3.8 it will stop working

已按照此答案How to use collections.abc from both Python 3.8+ and Python 2.7中的建议对我的manage.py文件进行了更改但仍然面临相同的错误。

import os
import sys

try:
    from collections.abc import Callable
except ImportError:
    from collections import Callable

if __name__ == "__main__":
    os.environ.setdefault("DJANGO_SETTINGS_MODULE","app.settings")
    try:
        from django.core.management import execute_from_command_line
    except ImportError as exc:
        raise ImportError(
            "Couldn't import Django. Are you sure it's installed and "
            "available on your PYTHONPATH environment variable? Did you "
            "forget to activate a virtual environment?"
        ) from exc
execute_from_command_line(sys.argv)
