Windows 7 : Facing issue in installing npm dependecies using "npm install" command

I am trying to install npm dependencies mentioned in package.json file using npm install command. One thing I would like to mention that I am in company's network but I tried using admin rights also. Still getting same error. Below is the error screenshot:

Here is my package.json file:

  "name": "gulp-autoreload",
  "description": "The simplest Live Reload environment",
  "version": "0.0.1",
  "dependencies": {
    "connect": "^2.14.4",
    "connect-livereload": "^0.5.3",
    "gulp": "^3.8.5",
    "gulp-livereload": "^3.8.0",
    "opn": "^1.0.1"
  "scripts": {
    "start": "gulp"

Please let me know what could be the problem.


For those who are behind a corporate web proxy:

Setting up Node.js and using npm can be a real pain. I thought that the web proxy settings would be like the rest of the unix world and require to set the HTTP_PROXY and HTTPS_PROXY environment variables. Although I just cloned the Node repository from Github so they are already setup. What gives?

A little searching and I discover that npm uses a configuration file and it can be added to via the command line npm config set .... The key to getting it right is the spelling of the settings. This has bit me so many times now! Getting npm to work behind a proxy requires setting the proxy and https-proxy settings. The key is noticing the - (dash) is not an _ (underscore).

So the full procedure is install Node.js via the installer or source. Open an command prompt or terminal session and run the following commands to configure npm to work with your web proxy. The commands use as the address and 8080 as the port

npm config set proxy 

npm config set https-proxy

You can check setting with :

npm config ls -l | grep prox
