Cannot find module bcrypt_lib.node error

[schnydszch]

Hi! While running npm install, I am getting error below:
"Cannot find module bcrypt_lib.node". I tried "npm install -g npm" because npm message says I need to upgrade to a newer version, so run that and I am now getting the error message below:
ERROR: npm v9.1.1 is known not to run on Node.js v11.14.0. You'll need to upgrade
to a newer Node.js version in order to use this version of npm. This version of
npm supports the following node versions: ^14.17.0 || ^16.13.0 || >=18.0.0. You
can find the latest version at https://nodejs.org/.

ERROR:
/root/.nvm/versions/node/v11.14.0/lib/node_modules/npm/lib/utils/exit-handler.js:22
const hasLoadedNpm = npm?.config.loaded

What could be the problem? TIA!
