Install Node.js modules on private LAN with NPM? - node.js

Question

I am trying to install node.js on a LAN that is not connected to the web. I've installed node.js with no problems, but it appears that npm wants to go out to the web, http GET https://registry.npmjs.org/moment so I can't install the modules that I need.
Here is the npm-debug file that is produced:

How can I install modules without connecting to the net?
Thanks

If you take a look at the docs, you'll see that you can install packages by simply passing a filesystem path or URL to a tarball that contains the package you want to install.
npm install http://server.on.lan/moment.tgz
Of course, if the package in question specifies any dependencies, npm will try to fetch them from the web. moment doesn't have any, so you should be able to just download the tarball and install it.
However, if you want to install other packages which do have dependencies, you might be better off setting up a npm registry mirror on your LAN.
