npm config set proxy null npm WARN cli npm v9.6.2 does not support Node.js v15.14.0.

Reason for the error: After installing Node, the version of npm was updated separately, resulting in a mismatch between the node version and the npm version. I need to install npm to a version corresponding to nodejs v15.14.0, the previous version | Node.js

Npm uninstall -g npm can replace npm with the previous version
