Download suitable(Python version, 32/64 bit) .exe file from http://pyyaml.org/wiki/PyYAML, then double click it to install PyYAML to your Windows 10 PC following the wizard window.

  1. Download the wheel from http://www.lfd.uci.edu/~gohlke/pythonlibs/#pyyaml that suits your need (Python version, 32/64 bit).

  2. $ pip3 install PyYAML-3.11-cp35-none-win32.whl

You will need to install many dependencies to get a proper build environment setup in Windows.

To make your life easy, there are use the windows installers (the .exe files) that correspond to your version of Python (so if you have installed 32 bit Python on 64bit Windows, use the 32bit installers).

The installers are listed on the PyPi index page for PyYAML.

The only drawback is that these installers will not work correct in a virtual environment, so you'll have to install them against the base version of Python.
