    For Windows installations:

    While running setup.py for package installations Python 2.7 searches for an installed Visual Studio 2008. You can trick Python to use a newer Visual Studio by setting the correct path in VS90COMNTOOLS environment variable before calling setup.py.

    If you have Visual Studio 2010 installed, execute

    SET VS90COMNTOOLS=%VS100COMNTOOLS%

    or with Visual Studio 2012 installed (Visual Studio Version 11)

    SET VS90COMNTOOLS=%VS110COMNTOOLS%

    or with Visual Studio 2013 installed (Visual Studio Version 12)

    SET VS90COMNTOOLS=%VS120COMNTOOLS%
