title: How to install pyYAML on windows 10
body: <p>Im trying to install pyYAML from source on windows 10. I downloaded PyYAML 3.11 from <a href="https://pypi.python.org/pypi/PyYAML" rel="noreferrer">https://pypi.python.org/pypi/PyYAML</a>. When I run setup.py I get error: [WinError 2] The system cannot find the file specified. How to fix it?</p>
