Step 1: Install a node version manager. We will use nvm. This is for OSx and Linux only.

If you are using fish shell then install fisher first:

curl -sL https://raw.githubusercontent.com/jorgebucaran/fisher/main/functions/fisher.fish | source && fisher install jorgebucaran/fisher

Then install nvm.fish.

fisher install jorgebucaran/nvm.fish

On bash shells you can install nvm directly.

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash

Step 2: Run

fnm install latest

to get the latest node release.

You can specify a node version by

fnm install 12

Step 3: select which node version you want to use with

fnm use 12

If on a non fish shell use nvm instead of fnm for all commands.
