Having trouble getting NPM to install dependencies with npm install -d in my project directory with a defined package.json file.

Here's my package.json: https://gist.github.com/3068312

And after wiping my project root's node modules folder (rm -rf node_modules), I run npm install -d in my project root and am greeted with this:

(ssh) /vagrant git:master ? npm install -d

npm not ok

If I rerun npm install -d, the error changes to whatever the next package is... if I keep running it it over and over again, it eventually doesn't complain anymore and outputs:

(ssh) /vagrant git:master ? npm install -d

However, none of the dependencies for any of these packages get installed. For instance, cheerio has a few dependencies, so when I try running my test suite, I'm greeted with:

(ssh) /vagrant git:master ? mocha --compilers coffee:coffee-script --watch spec/*                                                                                                                           


node.js:201
        throw e; // process.nextTick error, or 'error' event on first tick
              ^
Error: Cannot find module 'cheerio-select'
    at Function._resolveFilename (module.js:332:11)
    at Function._load (module.js:279:25)
    at Module.require (module.js:354:17)

What gives? I'm on Ubuntu Precise64 in a Vagrant virtual box.
