I’ll introduce the npm module avn, which automatically switches Node.js versions - it’s very convenient. (Last updated: 2017/04/15)

Try Switching Node.js Versions with avn

When you move to a directory that contains a .node-version file, avn automatically switches the Node.js version for you.

Sample .node-version

v12.16.2

$ cd ~/works/my_project
avn activated v12.16.2 (avn-nvm v12.16.2)

Since rvm, which nvm is based on, automatically switches Ruby versions, it’s nice to have similar behavior for Node.js.

That’s all from the Gemba, where I want nvm to automatically switch Node.js versions.
