Python - Pip Install - 代理错误 - '无法连接到代理。'，OSError'

Question

我想在企业 VM 中安装一些模块以创建一些 Python 脚本。我正在尝试使用 PIP 和 Proxy 来做到这一点。我正在使用这个命令行：

C:\Users\user>SET HTTPS_PROXY=https://user:pass@199.00.11.11:8080

C:\Users\user>SET PROXY=http://user:pass@199.00.11.11:8080

C:\Users\user>pip install datetime

为了访问我的虚拟机，我有以下凭据：

• 用户：NAN/用户
• 通过：通过

但我收到此错误：

Collecting datetime
  Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ProxyError('Cannot connect to proxy.', OSError('Tunnel connection failed: 407 Proxy Authentication Required ( Forefront TMG requires authorization to fulfill the request.

Access to the Web Proxy filter is denied.  )',))': /simple/datetime/
  Could not find a version that satisfies the requirement datetime (from versions: )
No matching distribution found for datetime

我需要做什么才能获得 python 模块？

就我而言，这只是因为 \xe3\x80\x90VPN\xe3\x80\x91 软件修改了 \xe3\x80\x90System Proxy\xe3\x80\x91 配置 \xe3\x80\x90IE\xe3\x80 \x91 浏览器。
