title: Unmet peer dependency webpack@3.6.0
body: <p>I am trying to run npm install on a project and it is unable to resolve webpack package. I have followed most of the other questions answers found in google and on here.</p>
  
  <p>I have completely cleaned computer of nodejs + npm files, again  by following answers on here :
  <a href="https://stackoverflow.com/questions/20711240/how-to-completely-remove-node-js-from-windows#20711410">How to completely remove node.js from Windows</a>
  <a href="https://stackoverflow.com/questions/41060769/unmet-peer-dependency-angular-2-3-0-rxjs-zone-js#42297654">Unmet Peer Dependency angular 2.3.0 rxjs zone.js</a></p>
  
  <p>I have tried to install the unmet dependencies manually, globally, persisting it to the package.json with npm install --save. Installing the specific versions it asks for and then also the latest versions. </p>
  
  <p>The error that I have is:
      UNMET PEER DEPENDENCY webpack@3.6.0</p>
