How to fix "SyntaxError: invalid syntax" for npm-update? - npm-update

Question

I'm currently having issues with some of my modules being outdated/missing for my Discord.js bot, so I want to use npm-update to fix my outdated/missing packages. When I go to use the command; I get a syntax error in the PowerShell window.
I've already tried updating npm and reinstalling it, no difference was made. Same error.

I expect npm to update all the packages/reinstall missing modules that the bot relies on, but I only get an error.
