python pip安装错误'无法获取基本索引URL'

Question

相当新的用户，但对命令行/python有基本的了解。尝试通过 windows 8 powershell 安装 pip 时收到以下错误消息：

Cannot fetch index base URL https://pypi.python.org/simple/
Could not find any downloads that satisfy the requirement pip
Cleaning up...
No distributions at all found for pip
Storing debug log for failure in C:\Users\xxxx\pip\pip.log

类似问题的其他实例似乎建议与代理有关，然后是一些更详细的 linux 说明。我不熟悉“代理”，但如果它是相关的，我在 chrome 中有一个 VPN 扩展。有人可以用简单的初学者语言建议为什么我会收到此错误消息/解决方法和命令提示行是什么？

问题在于捆绑的 SSL 证书似乎已过期。 检查您是否关注latest installation instructions 并更新您的 openssl 安装。
