npm ERR! not found: git

When I want to copy the ember-app-kit-master file in my project, I execute

cmd: cd C:\Users\hp-pc\Desktop\MyApp

then

cmd: npm install

But I got some errors:

npm ERR! not found: git
npm ERR!
npm ERR! Failed using git.
npm ERR! This is most likely not a problem with npm itself.
npm ERR! Please check if you have git installed and in your PATH.

npm ERR! cwd C:\Users\hp-pc\Desktop\MyApp
npm ERR! node -v v0.10.24
npm ERR! npm -v 1.3.9
npm ERR! code ENOGIT

This is part of my package.json :

 "repository": {
     "type": "git",
     "url": "git://github.com/stefanpenner/ember-app-kit.git"
  },
  "devDependencies": {
     "load-grunt-config": "git://github.com/Pradeek/load-grunt-config.git",
  }

When I remove settings about git, it works fine. Why is that?

Solution

You have to install Git-scm on your computer. NPM uses git to get the repos. Also, the command npm docs can be used with github to fetch the docs. So perhaps npm checks if got is installed. http://git-scm.com/downloads
