Npm errors when I try to install dependencies in loopback (strongloop) webapp

Question

I am new to NodeJS. I created a loopback (strongloop) webapp, but after that I try to run the command npm installin the application folder, I get this output in the terminal (the Ubuntu 14.04 server deleted the new updates - in the stray instance)

vagrant@vagrant-ubuntu-trusty-64:/vagrant/example-app$ npm install

This is the generated package.jsonone that was generated by the loopback framework:

{
  "name": "example-app",
  "version": "1.0.0",
  "main": "server/server.js",
  "scripts": {
    "pretest": "jshint ."
  },
  "dependencies": {
    "compression": "^1.0.3",
    "cors": "^2.5.2",
    "loopback": "^2.22.0",
    "loopback-boot": "^2.6.5",
    "loopback-datasource-juggler": "^2.39.0",
    "serve-favicon": "^2.0.1"
  },
  "optionalDependencies": {
    "loopback-explorer": "^1.1.0"
  },
  "devDependencies": {
    "jshint": "^2.5.6"
  },
  "repository": {
    "type": "",
    "url": ""
  },
  "description": "example-app"
}

I tried to run with sudo npm install, but I got exactly the same result.

Versions:

• Node v4.1.0
• Npm v2.14.3
• Vagrant 1.7.4
• Ubuntu Server 14.04.3 (with the latest updates)

Here is the npm-log file , it is very long.

If you know my mistake, feel free to just answer :)
