##Install a package - JQuery Use package manager npm

# npm list       
/root
└── (empty)

# npm install jquery
npm http GET https://registry.npmjs.org/jquery
npm http 200 https://registry.npmjs.org/jquery
npm http GET https://registry.npmjs.org/jquery/-/jquery-2.1.4.tgz
npm http 200 https://registry.npmjs.org/jquery/-/jquery-2.1.4.tgz
jquery@2.1.4 node_modules/jquery

# npm list
/root
└── jquery@2.1.4

Looks OK.

# ls
hw.js  node_modules  tmp

node_modules and tmp showed up after npm install

In order to use JQuery in node, you need jsdom 3.1.2. The latest jsdom does not work with node js anymore.

npm install -S 'jsdom@3.1.2'
