npm install failing when promisify-node is a dependency in my package.json

Hi --

I'm running into an issue with npm install with the following dependencies in my package.json:

"devDependencies": {
    "async": "^1.2.1",
    "bootstrap": "^3.3.5",
    "commander": "^2.8.1",
    "express": "^4.13.0",
    "grunt": "^0.4.5",
    "lodash": "^3.9.3",
    "marked": "^0.3.3",
    "moment": "^2.10.3",
    "nodegit": "^0.4.1",
    "promisify-node": "^0.1.5",
    "rimraf": "^2.4.0",
    "stopwords": "0.0.4",
    "string": "^3.3.0",
    "swig": "^1.4.2",
    "time-grunt": "^1.2.1",
    "yaml-front-matter": "^3.2.3"
  }

(The full package.json is here.)

npm install stopped working after I added promisify-node to the dependencies. After removing promisify-node the install succeeds. Also, perhaps interestingly, if I add promisify after installing nodegit, everything's fine.

The output from npm install seems to say there's an error in lifecycleScripts/install, and it's pretty obvious that the install script is having a problem with promisify-node.

Let me know if you need any more info. Thanks,

Start by reproducing the dependency-order failure with the listed package.json, Node v0.12.2, and npm 2.7.5. Inspect nodegit/lifecycleScripts/install and lifecycleScripts/retrieveExternalDependencies.js, focusing on the missing fs-extra error from promisify-node. Done means npm install succeeds with promisify-node present regardless of installation order.
