Solution  :

Update: Comments below point out that the instructions here may be dangerous. Consider using the Visual C++ 2008 Express edition and NOT using the original answer below. Original error message means Visual C++ 2008 is not installed

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 VS90COMNTOOLSenvironment variable before calling setup.py.

Execute the following command based on the version of Visual Studio installed:

  • Visual Studio 2010 (VS10): SET VS90COMNTOOLS=%VS100COMNTOOLS%
  • Visual Studio 2012 (VS11): SET VS90COMNTOOLS=%VS110COMNTOOLS%
  • Visual Studio 2013 (VS12): SET VS90COMNTOOLS=%VS120COMNTOOLS%
