body: <p>I tried upgrading my project from Angular 4 to Angular 6 and ran into some issues with webpack. I am getting the error "Cannot find module '@angular/cli/plugins/webpack'"</p>
  
  <p>Upon looking for the module.the cli folder now doesn't have a webpack.js file which was there before updating the cli version</p>
