无法安装python包SSL证书问题

Question

嗨，我安装了python版本3.9.6和pip版本21.1.3。我正在尝试运行py -m pip install Django，但我得到了以下错误：

WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None))

ERROR: Could not find a version that satisfies the requirement Django (from versions: none)
ERROR: No matching distribution found for Django

有谁能帮我，告诉我如何解决这个问题吗。

我试着关闭防病毒软件，但对没有帮助

我不能在我的cmd上使用openssl，如果有人知道如何一步一步地导入Django，这将对我有很大帮助，因为我刚开始使用python。

谢谢。

使用这个并工作

python -m pip install Django --trusted-host=pypi.python.org --trusted-host=pypi.org --trusted-host=files.pythonhosted.org
