pip设置代理（Windows）

一、命令行配置代理（临时）

pip install <name> --proxy http://<IP>:<port>

二、配置文件

• C:\ProgramData\pip\pip.ini（全局）
• %USERPROFILE%\pip\pip.ini（单用户）

pip.ini文件内容

[global]
proxy = http://<IP>:<port>

缺点：不开启代理的情况下会报错

WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ProxyError('Cannot connect to proxy.', NewConnectionError('<pip._vendor.urllib3.connection.HTTPSConnection object at 0x000001DA1684FCB0>: Failed to establish a new connection: [WinError 10061] 由于目标计算机积极拒绝，无法连接。'))': /simple/labelme/

三、环境变量

添加环境变量HTTP_PROXY和HTTPS_PROXY

• 使用命令行添加（管理员模式）

setx HTTP_PROXY "http://<IP>:<port>" /M
setx HTTPS_PROXY "http://<IP>:<port>" /M

注：https后面的地址是http开头，https会导致证书错误

\ Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLEOFError(8, '[SSL: UNEXPECTED_EOF_WHILE_READING] EOF occurred in violation of protocol (_ssl.c:1000)')': /pkgs/msys2/noarch/repodata.json.zst

缺点：不开启代理的情况下会报错

WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ProxyError('Cannot connect to proxy.', NewConnectionError('<pip._vendor.urllib3.connection.HTTPSConnection object at 0x000001DA1684FCB0>: Failed to establish a new connection: [WinError 10061] 由于目标计算机积极拒绝，无法连接。'))': /simple/labelme/
