    properly</code
  >. Try run <code>npm config ls -l</code>, this command will show all the

  change it to <code>http://registry.npmjs.org/ </code> as following command.

npm config set registry http://registry.npmjs.org/

<h2>Still not working!?</h2>
<p>
  Before trying to figure out what's happening, restart your command line again,
  might works. Also, it is better to use Node.js command prompt.
