npm WARN npm npm does not support Node.js v15.7.0

npm WARN npm can't make any promises that npm will work with this version.

any idea how can i fix it?
As per https://nodejs.org/en/download/ (as per today), it is mentioned as Latest LTS Version: 14.15.4 (includes npm 6.14.10)
Since node installation includes NPM also, you don't need to install it separately.
so cleanest way is to uninstall node from your machine and install it freshly which automatically gets you compatible NPM
i found the solution: https://github.com/nodejs/help/issues/2874#issuecomment-663661148
i deleted npm and npm cache folders in Appdata>Roaming and then reinstalled nodejs
