Question

我正在尝试使用下面的pip install命令,但它失败了代理身份验证需要问题.我已经在RHEL7.x服务器中配置了代理.

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

安装要安装的软件包：

:\pip install PackageName

Answer 2

错误407意味着代理的身份验证丢失/错误。'从username:pwd零件上取下，即使用：pip install --proxy https://username:pwd@proxy:host。

作为另一种选择，在安装 Python 包之前尝试从该服务器打开 Internet 连接。
