title: NPM cannot find module 'date-fns/local/en-US' in react-date-range package
body: <p>I've been using package <code>react-date-range</code> for some time now. After installing some other package, my app suddenly crashes with the following error message as I do <code>npm start</code></p>
  
  <p><a href="https://i.stack.imgur.com/gtXrM.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/gtXrM.png" alt="Error message from npm"></a></p>
  
  <p>I have <strong>NO</strong> idea where this is coming from. Tried re-installing the packages after removing them, but it still complains about the missing <code>module</code>.</p>
  
  <p>Here is my <code>package.json</code> file. (Don't mind the mixture of <code>material-ui</code> and <code>bootstrap</code> for the front-end)</p>
  
  <p>Many thanks!</p>
