title: NPM install Gulp/Elixir
body: <p>I'm following a course online and have downloaded Node and NPM.</p>
  
  <p>I have done a package.json file and are have some problems with
  the installation.</p>
  
  <p>I really don't understand the error message. I had the latest
  version of Node, I tried to downgrade the version to 6.10.3 (the same version in the online course) but I still don't work. </p>
  
  <p>Is there someone here that knows what the problem can be? I'm new at this and not so experienced with the error messages. </p>
