Cannot install Node modules

I am trying to install node modules but getting the following long list of errors.

Error Screenshot

I am using command like npm install -g ionic or npm install -g cordova.

What I have tried so far-

  1. I have tried removing and reinstalling latest version of Node.js
  2. I have tried installing 32 and 64 bit versions of Node.js
  3. I have also tried setting the --registry parameter to http://registry.npmjs.org/ and https://registry.npmjs.org/.
  4. I have tried running command prompt and git bash shell as Administrator.

Notes:

  • I am working on Windows 8.1 Pro 64 bit.
  • I am not behind any firewall or proxy. All my internet work perfect.
  • I have turned my windows firewall off as well.

Please help. Any help is highly appreciated.
