title: Cannot find module '@babel/plugin-transform-react-jsx-source' when running React App
body: <p>I have just created a React App with <code>create-react-app aquastars</code> and then eject the dependencies using <code>yarn run eject</code> and when I run the app I get the following error.</p>
  
  <blockquote>
    <p>Cannot find module '@babel/plugin-transform-react-jsx-source'</p>
  </blockquote>
  
  <p>I haven't done anything!  What do I need to do to get this up and running?  Any help would be appreciated.</p>
