npm install hangs

This is my package.json:

{
"name": "my-example-app",
"version": "0.1.0",
"dependencies": {

  "request": "*",
  "nano": "3.3.x",
  "async": "~0.2"
  }
}

Now, when I open the cmd and run npm install, the install hangs. What am I doing wrong?

I had the same problem. The reason - wrong proxy was configured and because of that npm was unable to download packages.

So your best bet is to the see the output of

$ npm install --verbose

and identify the problem. If you have never configured proxy, then possible causes can be

  • Very outdated npm version.
  • Some problem with your internet connection.
  • Permissions are not sufficient for npm to modify files.

I am behind a corporate proxy, so I usually use an intermediate proxy to enable NTLM authentication.

I had hangs problem with npm install when using CNTLM proxy. With NTLM-APS (a similar proxy) the hangs were gone.

*Try doing sudo npm install.

*If you're using github then it could be you don't have permission and need to generated a public SSH key and add it to your settings account: (https://help.github.com/articles/generating-ssh-keys/)
