Is this an error with del? Tried to reinstall del. Didn't work. :/

Tried to install a module called def (npm install def --save-dev), but then I got this error:

I am the BIGGEST IDIOT. In my gulpfile.js, instead of requiring del, I required def, and assigned it to del.

const del = require('def');

It works now.

Leaving my question here to show the importance of checking for dumb typos. WOW. Haha
