title: typescript that said has no exported member MyModule
body: <p>I just wrote an npm package with parcel + typescript + react.<br>
  <a href="https://github.com/Kamva/kamva-ui-kit" rel="nofollow noreferrer">https://github.com/Kamva/kamva-ui-kit</a></p>
  
  <p>when I published it I faced to an error from typescript that said has no exported member 'Button'.
  I can't figure out why this issue happening.</p>
  
  <p><code>import { Button} from "@kamva/ui-kit";</code></p>
  
  <p>Is there anyone have the same problem or help me?</p>
