Using NVM to get the most up-to-date version of node

NVM allows you to install and run different versions of node (and to manage and install their "global packages" separately).

First download the git repo

git clone --depth 1 https://github.com/creationix/nvm.git

(We recommend a shallow clone to avoid cloning the whole nvm git history. With the --depth 1option we instruct git to copy only the latest revision of the repo, which will take considerably less disk space.)

Now hook up your shell to use nvm

source ~/nvm/nvm.sh

To automatically run this every time you start a bash shell, add it to your bashrc by running this Bash command (once only):

echo 'source ~/nvm/nvm.sh' >> ~/.bashrc

You can now do a nvm ls-remote to see what versions of node are available, and then install them. Here's how you'd install v6.11.4 for example:

nvm ls-remote
#...
nvm install v14.16.0

You can run nvm use v14.16.0 to use the new node. To set that as default, set up an nvm alias:

nvm alias default v14.16.0

This will also solve any permission problems involved with installing with npm install --global -- it will work without needing to specify a prefix.
