title: Duplicate identifier 'LibraryManagedAttributes'
body: <p>I have the same issue as in:</p>
  
  <p><a href="https://stackoverflow.com/questions/52339225/react-typescript-2312-14-duplicate-identifier-librarymanagedattributes">React typescript (2312,14): Duplicate identifier &#39;LibraryManagedAttributes&#39;</a></p>
  
  <p>and</p>
  
  <p><a href="https://stackoverflow.com/questions/52323056/typescript-error-duplicate-identifier-librarymanagedattributes">TypeScript error: Duplicate identifier &#39;LibraryManagedAttributes&#39;</a></p>
  
  <p>But I just can't find any solution.</p>
  
  <p>I already upgraded to the latest node/npm/yarn/typescript versions. Also tried downgrading. Nothing helps.</p>
  
  <pre><code>yarn build --verbose
  yarn run v1.9.4
  $ react-scripts-ts build --verbose

  (2312,14): Duplicate identifier 'LibraryManagedAttributes'.
  
  
  error Command failed with exit code 1.
  </code></pre>
  
  <p><code>--verbose</code> somehow doesn't give me more information.</p>
  
  <p>As I can see <code>LibraryManagedAttributes</code> is defined in:</p>
  
  <ul>
  <li><code>node_modules/@types/react/index.d.ts</code></li>
  <li><code>node_modules/@types/prop-types/node_modules/@types/react/index.d.ts</code></li>
  <li><code>node_modules/@types/react-overlays/node_modules/@types/react/index.d.ts</code></li>
  <li>....</li>
  </ul>
  
  <p><strong>Where is this coming from? How can I avoid that?</strong></p>
  
  <p>I want to find out where this error is coming from so that I can report it to the right entity but I don't know where to start.</p>
  
  <p><strong>What else can I try?</strong></p>
