title: Why Scrollspy is not loaded in react app?
body: <p>I have <code>npx create-react-app</code> project. It was working good on older system but not working in my new mac. Wonder why Scrollspy can not be loaded. Got following error on <code>npm start</code></p>
  
  <pre><code>./src/components/MyComponent.js
  Cannot find file: 'Scrollspy.js' does not match the corresponding name on disk: 
  './node_modules/react-scrollspy/lib/scrollspy.js
  </code></pre>
  
  <p>In <code>MyComponent.js</code>, I have imported <code>Scrollspy</code> like:</p>
  
  <pre><code>import Scrollspy from 'react-scrollspy';
  </code></pre>
