title: eslint error showing with webpack alias
body: <p>In my <code>webpack</code> config. I defined aliases</p>
  
  <pre><code>alias: {
              components: 'src/components/',
              config: 'src/config/'
  }
  </code></pre>
  
  <p>When I import a module from this path an eslint error occurred.</p>
  
  <pre><code>import ShadowWrapper from 'components/ShadowWrapper'
  </code></pre>
  
  <p>error 'components' should be listed in the project's dependencies. Run 'npm i -S components' to add it import/no-extraneous-dependencies</p>
