How to install all files from a repository via npm install?

Question

JavaScript

I have a package.json file in my project. I list the dependencies in it. In it, I specify the dependency on jquery v1.11.1, and assign it a link to https://github.com/jquery/jquery/tarball/1.12-stable . All files are downloaded in the browser. But when installing via npm install, all files listed in .npmignore are ignored. How do I tell npm to download all files?
