How to upgrade to popperjs/core via package.json: name can only contain URL-friendly characters?

Question

So, I wanted to upgrade my package.json stack due to a harmless deprecation warning:

npm WARN deprecated [email protected]: You can find the new Popper v2 at @popperjs/core, this package is dedicated to the legacy v1

Turns out popper.js is deprecated and replaced by popperjs/core. But there's a slash in that name.

npm ERR! Invalid package name "popperjs/core": name can only contain URL-friendly characters

Looks like the author of this new repo decided to have a / in the name which breaks my package.json. Any ideas how to approach this?

In my package.json, I call list "popperjs/core": "2.5.2" which prompts the URL-unfriendly naming.

Answer 1

So, apparently, it just needs an @ in front: "@popperjs/core": "2.5.2"
