Error returned when running npm install on package.json which contains symbolic links

When I run npm install, I get the an error output that I'm not sure how to interpret.

A package.json was created by a colleague, and contains a path for preinstall. He runs Mac, and I'm running Windows 7.

First, the package.json: { "name": "package name", "description": "description", "readme": "?", "version": "0.0.1", "private": true, "main": "main.js", "scripts": { "preinstall": "../../etc/directory_with_files" }, "dependencies": { "aa-moduleName": "^0.0.1" }, "engines": { "node": ">=0.10.0" }, "repository": {} }

Next, the error output:

myApp@0.0.1 preinstall: ../../etc/directory_with_files

../../etc/directory_with_files

'..' is not recognized as an internal or external command.
