After my machine updated automatically, NPM is not working any more

OS: Ubuntu 20.04.3 LTS
npm -v: 8.1.4
node -v: v10.19.0

Every time I try to start something with NPM, it gives me the same error message:

*@*:~$ npm help

CodePudding user response：

Upgrade your node version, you're using the newest npm version, and it doesn't support old versions of node

Since you're on ubuntu i recommend you to use nvm

sudo apt-get install nvm

nvm install 16
nvm use 16
