Pip unable to access websites, fresh install of Python 2.7.9

问题

I just did a fresh/clean install of Python 2.7.9 to get pip (couldn't get it any other way) and now when I go to install something using it I get this error:

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

The error log looks similar, just many time out messages with no more information:

I'm assuming that this is a network thing, is there any work around?

回答1:

It seems like a network problem.

If you can open https://pypi.python.org/simple/openpyxl/ in your browser, then it may be some other issue.

回答2:

It appears you are behind a firewall on your corporate campus and need a proxy to make HTTP requests outside your local network. You will need to specify your proxy server in your shell before running pip:

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

You can also specify a proxy directly to pip, but I understand this feature was broken at one point:

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

However, we cannot determine your proxy information, you will need to do that. You may have some luck with:

import urllib2
print urllib2.getproxies()
