I am receiving above error message when I try to run gatsby develop on my windows 10 x64 machine. I am using node version 8.4.0 and npm version 5.3.0

Any help or suggestions would be welcome,

It happens sometimes for me on windows that npm won't install packages correctly - usually deleting node_modules directory and rerunning npm install fixes this for me

@wisemonkey47 it looks like Python isn't installed or setup correctly. Try following the instructions on this page to setup the necessary dependencies for Gatsby on Windows https://www.gatsbyjs.org/docs/gatsby-on-windows/
