EACCES permission error while installing the Dev Server - Installing nvm (Node Version Manager)

Site URL: https://llama-shallot-7yz9.squarespace.com

I'm getting the standard EACCES: permission denied when I try to run: 

npm install -g @squarespace/server

The squarespace docs direct you to the npm docs here. The npm docs say:

Quote

"You do not need to remove your current version of npm or Node.js before installing a node version manager."

However speaking with a friend he said that you actually do need to uninstall npm and Node.js?

I'm currently backing up my Mac with time machine, and I'm going to give this a whirl to see if it solves my issue: https://ajaykarwal.com/uninstall-node-and-install-nvm

Does anybody have some experience and can shed some light? I'm working on MacOS Big Sur.

Thanks in advanced.

It's been awhile since I've installed the dev server on macOS but would a sudo do? Yes I know there are arguments on the good and bad of doing it this way. Let's not dig into that. If you want the scoop on the pros can cons hit the search engines.
