title: npm link, not install, package.json dependencies
body: <p>I  want to local link all the explicit dependencies stated in my <code>package.json</code>. </p>
  
  <p>If I just try  <code>npm link</code> what I get is a local install of all of the packages, independently of whether or not they are already globally installed. </p>
  
  <p>I didn't expect that. What I expected, and what I needed, is a behavior similar as if I'd do a <code>npm link package</code>. I wanted <code>npm link</code> to inspect the dependencies in <code>package.json</code> and for each of the, to create the link, and do a global install if needed.</p>
