[英]Pip won't let me install anything
Just setting up my python environments here.只需在此处设置我的 python 环境。 An absolute newb if you must say.
如果您必须说,绝对是新手。
Background information: Currently at a place that requires a proxy to be set.背景信息:目前在需要设置代理的地方。 I do this by using the Manual Proxy Settings in Wondows Settings.
我通过使用 Wondows 设置中的手动代理设置来做到这一点。
I did go ahead and add http_proxy, https_proxy, and socks_proxy to my system variables as follows HTTP_PROXY http://10.8.0.1:8080 HTTPS_PROXY https://10.8.0.1:8080 ALL_PROXY socks5://10.8.0.1:8080 I did go ahead and add http_proxy, https_proxy, and socks_proxy to my system variables as follows HTTP_PROXY http://10.8.0.1:8080 HTTPS_PROXY https://10.8.0.1:8080 ALL_PROXY socks5://10.8.0.1:8080
Any and everytime I type in to install any package through pip, I write the command "pip install package_name" on my powershell terminal, I get the error,每次我输入安装任何 package 到 pip 时,我都会在 powershell 终端上写命令“pip install package_name”,我得到错误
Defaulting to user installation because normal site-packages is not writeable

What am I supposed to do?我应该做些什么? Another answer on stackoverflow which I am assuming is for the same problem is to downgrade urlib3 using "pip install urllib3==1.25.11" but I literally can't use pip because all I'd get is the same error.
我假设的关于stackoverflow的另一个答案是针对相同的问题是使用“pip install urllib3 == 1.25.11”降级urlib3,但我实际上不能使用pip,因为我得到的都是相同的错误。
I have since also tried to install and reinstall python.从那以后,我还尝试安装和重新安装 python。 Even went from 3.9.5 to 3.8.10 but the problem still persists.
甚至从 3.9.5 到 3.8.10 但问题仍然存在。
Please help请帮忙
(To make my comment an answer:) (让我的评论成为答案:)
The HTTPS proxy should probably not be using the https:// protocol itself, so HTTPS 代理可能不应该使用 https:// 协议本身,所以
HTTP_PROXY=http://10.8.0.1:8080
HTTPS_PROXY=http://10.8.0.1:8080
should be the more correct environment variables.应该是更正确的环境变量。
Have you created a local environment using something like您是否使用类似的东西创建了本地环境
python.exe -m venv env
python.exe -m venv env
? ? It seems like you are trying to install packages on the main python install
您似乎正在尝试在主 python 安装上安装软件包
