Failed at the node-sass@3.13.1 postinstall script

I'm constantly getting this error when running 'gulp' 'npm install gulp': 

Failed at the node-sass@3.13.1 postinstall script

This command fixes it every time: 

npm install node-sass@latest

If that doesn't work, take the next steps: 

Delete the package-lock.json file. 

Remove gulp-sass from package.json. 

Reinstall gulp-sass: 

npm install gulp-sass --save-dev
