Python - Pip 安装 - 代理错误 - 'Cannot connect to proxy.'，OSError'

Question

我想在企业 VM 中安装一些模块以创建一些 Python 脚本。我正在尝试使用带有代理的 PIP 来做到这一 pip 。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

要访问我的虚拟机，我有以下凭据:

用户 : NAN/用户

通过 :通过

但我收到此错误:

Collecting datetime

  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？

试试这样:

set HTTP_PROXY=http://199.00.11.11:8080
set HTTPS_PROXY=https://199.00.11.11:8080
