只是在这里设置我的python环境。一个绝对的新手，如果你必须说的话。
背景信息：目前在一个需要设置代理的地方。我通过使用Windows设置中的手动代理设置来做到这一点。
我确实继续将http_proxy、https_proxy和socks_proxy添加到我的系统变量中，如下所示HTTP_PROXYhttp://10.8.0.1:8080HTTPS_PROXYhttps://10.8.0.1:8080ALL_PROXYsocks5://10.8.0.1:8080
每当我通过pip输入安装任何软件包时，我都会写下命令"；pip安装软件包名称"在我的powershell终端上，我得到了错误，

我该怎么办？关于stackoverflow的另一个答案，我认为是针对相同的问题的，是使用"；pip-install-urllib3＝＝1.25.11"；但我真的不能使用pip，因为我得到的都是相同的错误。
从那以后，我也尝试安装和重新安装python。甚至从3.9.5到3.8.10，但问题仍然存在。
请帮助
(让我的评论成为一个答案：(
HTTPS代理可能不应该使用HTTPS://协议本身，因此
HTTP_PROXY=http://10.8.0.1:8080
HTTPS_PROXY=http://10.8.0.1:8080
应该是更正确的环境变量。
我还找到了建议降级urllib3==1.25.11的答案。据我所知，您可以尝试从本地安装urllib3。
pip install <path-to-package>
在这里下载包
您是否使用之类的东西创建了本地环境
python.exe-m venv env
？看起来你正试图在主python安装上安装软件包
