    fairly new user but have basic understanding of command line/python. when attempting to install pip through windows 8 powershell get the following error message:

    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


    other instances of similar question seem to suggest something to do with proxy and then some more detailed linux instructions. i am unfamiliar with 'proxy' though if it's relevant i have a VPN extension in chrome. could somebody please suggest in simple, beginner language why i'm getting this error message/what the workaround and command prompt line would be?

    appreciate it
