I'm new to Wordpress development and npm. My goal is to get started creating and editing a website on my computer locally. I followed the "Get Started with Gutenberg in Wordpress" guide from Professor K Explains, which in turn follows the "@wordpress/env" and (mostly) "@wordpress/create-block" guides on Wordpress.org.

This essentially involved installing dependencies: Node.js, Docker, and Git (which I already have), making sure Docker is running (running systemctl start docker if not), followed by npx @wordpress/create-block new-example-block and some other commands following it (which I do not believe are relevant to this issue). On my first attempt, I created a block that runs a local instance of a website successfully.

However, I want a different title for the block, so I tried to create a new one. When I try this again however, running npx @wordpress/create-block new-example-block and npx @wordpress/create-block@latest new-example-block-2 both fail, resulting in a whole host of errors and warnings. (npx @wordpress/create-block@latest is what is currently listed on "@wordpress/create-block", so this line from the article is probably more updated than the one from the video. It still fails, however.)

Let me know if you need the whole thing. It's so long I wasn't sure how I should include it.

Most of what I found online was related to the access tokens, though none to Wordpress's create-block process specifically.

Various websites suggested creating a new npm account with npm adduser followed by npm login, but that did not solve the issue. I don't exactly know how it would, as I don't know what access token I was supposed to have, given I did not need to make an account or log in when npx ran successfully the first time.

Other websites suggested moving/removing the .npmrc file in my home/[user] directory. That also failed to do anything.

Lastly, this DevErrors article suggested to follow up the removal of .npmrc by clearing the cache and reinstalling, as below.

npm cache clean --force
rm -rf node_modules package-lock.json
npm install

It still seems to generate the same errors.

I don't really understand what the problem is with access tokens, dependencies, or the @wordpress/vips package. How do I go about solving this issue?
