set default nvm version: nvm alias default 6.11.5 if you want it pegged to that specific version.

You can also do nvm alias default 16 or nvm alias default node.

Either way, you’ll want to upgrade to the latest version of nvm (v0.39.2 as of this writing)

# nvm set default node.js version 16.14.2
$ nvm alias default 16.14.2
$ nvm use

$ node -v
# v16.14.2
