These answers are all about updating the version of Node, when the original question is about updating the version of the NVM tool itself.

The script to update NVM is:

$ curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.8/install.sh | bash

and you can find the list of the latest releases here: https://github.com/nvm-sh/nvm/releases

Stable vs. experimental versions

Versions with even numbers such as 18.x are stable.

Versions with odd numbers such as 19.x are unstable/experimental.

See https://nodejs.org/en/

Install latest LTS version

LTS (Long Term Support) is the stable version.

Depending on platform, either nvm install lts on Windows or nvm install --lts on Linux installs the latest LTS version.

Select installed version

If you had, say, 17.x installed, you now also have, say, 18.x installed.

Now, you need to select the newly installed version with nvm use 18.13.0.

This may work:

nvm install NEW_VERSION --reinstall-packages-from=OLD_VERSION

For example:

nvm install 6.7 --reinstall-packages-from=6.4

then, if you want, you can delete your previous version with:

nvm uninstall OLD_VERSION

Where, in your case, NEW_VERSION = 5.4 OLD_VERSION = 5.0

Alternatively, try:

nvm install node --reinstall-packages-from=current

Or you can update to the last long-term support version with

nvm install lts --reinstall-packages-from=current

nvm install 8.10.0 is for installing proposed node version locally.

In order to use it:

nvm use 8.10.0

Note that you need to run this command as administrator.

You can always set default Node.js version:

nvm alias default 8.10.0
