  • Gyp requires Python, it's telling you that. Do you have Python installed? – Sam H. Mar 31 '18 at 18:18
  • @SamH. i do not know. What am i supposed to do to install it or check if it is present – M.A.G Mar 31 '18 at 18:22
  • It you type python into the command line and got enter, does it open a Python REPL or throw an error? – Sam H. Mar 31 '18 at 18:23
  • @SamH. it throws an error that the term python is not recognized – M.A.G Mar 31 '18 at 18:30

You need Python 2.7.x for this to work on your machine. Your windows machine is missing essential build tools.

Install windows build tools from npm.

npm install --global --production windows-build-tools
