Go to your terminal and type in

npm install 

This will crawl through all the required packages mentioned in package.json and download it to node_modules folder.

When using gulp in your gulpfile.js

var install = require("gulp-install");

gulp.src(['./bower.json', './package.json'])
.pipe(install());

So when you run gulp in your terminal all the packages in bower.json and package.json will be downloaded into bower_components and node_modules, respectively.
