Can't install gulp-sass, what's not to like?

Question

npm

Installed galp and trying to install sass compilers but nothing good comes of it, here is my package.json:

package.json

{
  "dependencies": {
    "gulp": "^4.0.2"
  },

  "name": "gulptest",
  "version": "1.0.0",
  "main": "index.js",
  "devDependencies": {
    "gulp-sass": "^4.1.0",
    "gulp-sourcemaps": "^3.0.0",
    "gulp-watch": "^5.0.1"
  },
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "description": ""
}

And the errors themselves:
