Install Node / NPM via Homebrew
Homebrew is a package manager for Mac, if you haven’t already installed it go ahead and follow this link https://brew.sh/
To install node run these commands.
$ brew update $ brew uninstall node $ brew install node $ brew postinstall
Note: the uninstall node may fail if you don’t have node installed on your machine currently, this just makes sure to remove any hangover files from potential previous installs.
