Hi, last time i posted the same problem for MAC and it started working when i got answer on the topic.
as NVM is not available for windows so i installed the node.js with .exe file from the node js website.
i have all the requirements installed on my PC.
i am getting following errors.
C:\xampp\htdocs\sage\wp-content\themes\sage>gulp watch
module.js:339
throw err;
