authentication - pip 安装失败，需要 407 代理身份验证

Question

我正在尝试使用下面的 pip install 命令，但它因需要代理身份验证而失败。我已经在我的 RHEL7.x 服务器中配置了我的代理。

Command Used: `pip install --proxy https://'username:pwd'@proxy:host  --upgrade pip`

日志:

Retrying (Retry(total=4, connect=None, read=None, redirect=None)) after connection broken by 'ProxyError('Cannot connect to proxy.', error('Tunnel connection failed: 407 Proxy Authentication Required',))': /simple/pip/
Retrying (Retry(total=3, connect=None, read=None, redirect=None)) after connection broken by 'ProxyError('Cannot connect to proxy.', error('Tunnel connection failed: 407 Proxy Authentication Required',))': /simple/pip/
Retrying (Retry(total=2, connect=None, read=None, redirect=None)) after connection broken by 'ProxyError('Cannot connect to proxy.', error('Tunnel connection failed: 407 Proxy Authentication Required',))': /simple/pip/
Retrying (Retry(total=1, connect=None, read=None, redirect=None)) after connection broken by 'ProxyError('Cannot connect to proxy.', error('Tunnel connection failed: 407 Proxy Authentication Required',))': /simple/pip/
Retrying (Retry(total=0, connect=None, read=None, redirect=None)) after connection broken by 'ProxyError('Cannot connect to proxy.', error('Tunnel connection failed: 407 Proxy Authentication Required',))': /simple/pip/

Answer 1

这是您应该尝试的第一件事:

打开命令提示符(CMD)。

导出代理设置:
:\set http_proxy=http://username:password@proxyAddress:port:\set https_proxy=https://username:password@proxyAddress:port
安装你要安装的包:
:\pip install PackageName
