github very irritating condition or not finding local repo directory and not able to edit files

after an hour of messing around with git (new to its use) im just not able to find the git repo directory to edit the package.json file because im trying to install this

https://github.com/davidcoallier/node-php/blob/master/README.md

and as soon i run the

npm install

i get this error

npm WARN package.json nodephp@0.1.1 Invalid dependency: fastcgi 1

now i understand i need to update the repo within that json file but windows fails to find it. could someone assist me in finding this or a work around for this.
