The problem is with installing node modules on Windows machine (some of them). To fix that you need:

1. Have node version 3+.
2. Install Python 2.7. If I understood correctly - you need exactly that version.
3. Set environment variable for the python. For example: set PYTHON=C:\Python\bin\Python.exe
