Question

我刚刚完成了一个新的/干净的Python 2.7.9安装来获取pip（无法通过任何其他方式获得它），现在当我使用它安装一些东西时，我收到了这个错误：

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

错误日志看起来很相似，只有很多超时消息没有更多信息：

我假设这是网络的事情，有什么工作吗？

Answer 1

这似乎是一个网络问题。

如果您可以在浏览器中打开https://pypi.python.org/simple/openpyxl/，则可能是其他问题。

Answer 2

您的企业园区内的防火墙似乎已经落后，需要一个代理才能在本地网络外发出HTTP请求。在运行pip之前，您需要在shell中指定代理服务器：

SET HTTPS_PROXY=<proxyHost>:<proxyPort>
SET HTTP_PROXY=<proxyHost>:<proxyPort>

您也可以直接为pip指定代理，但我知道此功能在某个时刻被破坏了：

pip install <package> --proxy=<proxyHost>:<proxyPort>

但是，我们无法确定您的代理信息，您需要这样做。你可能会有运气：

import urllib2
print urllib2.getproxies()

Pip无法访问网站，全新安装Python 2.7.9
