Windows 8.1 中需要 407 代理身份验证

Question

我正在尝试使用 pip install numpy 在 Windows 8.1 中安装 numpy。

它给出以下错误：

Collecting numpy
  Retrying (Retry(total=4, connect=None, read=None, redirect=None)) after connec
tion broken by 'ProxyError('Cannot connect to proxy.', OSError('Tunnel connectio
n failed: 407 Proxy Authentication Required',))': /simple/numpy/
  Retrying (Retry(total=3, connect=None, read=None, redirect=None)) after connec
tion broken by 'ProxyError('Cannot connect to proxy.', OSError('Tunnel connectio
n failed: 407 Proxy Authentication Required',))': /simple/numpy/
  Retrying (Retry(total=2, connect=None, read=None, redirect=None)) after connec
tion broken by 'ProxyError('Cannot connect to proxy.', OSError('Tunnel connectio

  Retrying (Retry(total=1, connect=None, read=None, redirect=None)) after connec

  Retrying (Retry(total=0, connect=None, read=None, redirect=None)) after connec

n failed: 407 Proxy Authentication Required',))': /simple/numpy/
  Could not find a version that satisfies the requirement numpy (from versions:
)
No matching distribution found for numpy

引用this 后，我在cmd 中运行以下命令：

set proxy proxy-server="http=202.141.80.19:3128;https=202.141.80.19:3128" 

出于身份验证的目的，我也尝试过：

set proxy proxy-server="http=username:password@202.141.80.19:3128;https=username:password@202.141.80.19:3128" 

但它不起作用。

如何摆脱这个错误？

经过多次尝试，这帮助我继续工作。

set HTTP_PROXY=http://proxy_userid:proxy_password@proxy_ip:proxy_port
set HTTPS_PROXY=http://proxy_userid:proxy_password@proxy_ip:proxy_port
