laravel-elixir Causing `npm install` to Error and cannot run `gulp` - node.js

Question

I am having an issue with adding laravel-elixir to my package.json file in order to run gulp. When I run the command $ gulp i receive an error stating that laravel-elixir module cannot be found. So, adding the module to my package.json file then running npm install causes an error. (npm install works fine without the laravel-elixir module in package.json)
I have read through all the documentation and have ensured everything is installed. This seems to be a bit of an issue from what i have researched (sorry in advanced if this might be a dublicate). I just cannot seem to find the fix here. Please comment and let me know if you need to see the errors or anything.

Answer 1

Try installing python first , since it is searching for the executable and unable to find it
