title: Why is the system looking for 'react-is` inside `prop-types`?
body: <p>For some reason, the system's looking for something called <code>react-is</code>, leading to this error:</p>
  <pre><code>Failed to compile.
  
  ./node_modules/prop-types/node_modules/react-is/index.js
  Error: ENOENT: no such file or directory, open 'C:\Users\mikwee\linkroots\node_modules\prop-types\node_modules\react-is\index.js'
  </code></pre>
  <p>It is a package, but it's looking for it inside <code>prop-types</code> for some reason. This error started when I imported a React Bootstrap component. I'm not sure what other info to add here, so if you need to know more, let me know please!</p>
