title: tslint update error "Cannot find module 'tslint/lib/lint'"
body: <p>We recently upgraded our Angular 2 project to <code>@angular/cli</code> version 1.0.  We also upgraded <code>tslint</code> from <code>2.x</code> to <code>5.x</code>.  Now we receive the following <code>tslint</code> error at design time (in VSCode Output terminal).</p>
  
  <blockquote>
    <p>Cannot find module 'tslint/lib/lint' while validating.</p>
  </blockquote>
  
  <p>I've attempted to follow several github thread suggestions including removing deprecated rules and adding new rules, rolling back <code>tslint</code> to a previous version and completely uninstalling and reinstalling <code>@angular/cli</code> and associated modules.  </p>
  
  <p>However, this error continues to arise and it's preventing <code>tslint</code> from evaluating our code.</p>
  
  <p>A previous SO post cited the same error message but apparently for a different reason; the accepted answer did not resolve my issue:
