Whether npm or other front-ent package manager tools are all writtent by node, therefor, if we want to use it, we should install node at first.

After installing node, we will get npm to manage your javascript packages.
As we all know, npm is a package manager for JavaScript and word‘s largest software register. Recently, I found a tool like npm and more stronger than npm on mac system, that is Hombrew. So maybe you will ask what‘s the difference between npm and homebrew
- Difference between homebrew and npm
This is a rough, inaccurate answer, but it’s very easy to understand and it can give you a quick preview: Homebrew is like the Mac App Store: it installs softwares that can be used in the whole system. npm is like the Extension manager in Chrome: it can only add function extensions within a single app.
- Installation
$ npm install homebrew
For now, maybe you want to install different node version on one operating system, then "nvm" will help you solve this problem.
https://github.com/creationix/nvm/blob/master/README.md
you can use bellow command to check node version or other nvm commands
