title: Can I install a NPM package from javascript running in Node.js?
body: <p>Can I install a NPM package from a javascript file running in Node.js?  For example, I'd like to have a script, let's call it "script.js" that somehow (...using NPM or not...) install a package usually available through NPM.  In this example, I'd like to install "FFI".  (npm install ffi)  </p>
