Error to upgrade: from 6.14.8 to the latest

[John-saint]

I am getting an error message while upgrading npm, maybe I was a bit too rush 🙄

You wanted to install npm 7.0.7, but the installed version is 6.14.8.

A common reason is an attempted "npm install npm" or "npm upgrade npm". As of today, the only solution is to completely uninstall and then reinstall Node.js. For a small tutorial, please see https://github.com/felixrieseberg/npm-windows-upgrade#usage.

Please consider reporting your trouble to https://aka.ms/npm-issues.
