Why do I get an error when installing plugins for grunt?

Question

JavaScript

I created 2 files package.json and Gruntfile.js I wanted to install these packages, in the first I write:

{
  "name": "css3-bottom-generator",
  "version": "0.1.0",
  "devDependencies": {
    "grunt": "~0.4.5",
    "grunt-contrib-jshint": "latest",
    "grunt-contrib-concat": "latest",
    "grunt-contrib-nodeunit": "~0.4.1",
    "grunt-contrib-uglify": "latest",
    "grunt-contrib-cssmin": "latest",
    "grunt-contrib-watch": "latest",
    "grunt-remove-logging": "latest",
  }
}

I try to install using the command npm install grunt --save-dev, thinks and an error occurs. here are the logs
