  <pre><code>error: Error: Unable to resolve module `@react-navigation/stack` from `src\nav\nav.js`: @react-navigation/stack could not be found within the project.
  
  If you are sure the module exists, try these steps:
   1. Clear watchman watches: watchman watch-del-all
   2. Delete node_modules: rm -rf node_modules and run yarn install
   3. Reset Metro's cache: yarn start --reset-cache
   4. Remove the cache: rm -rf /tmp/metro-*

  <p>I've tried many things including using yarn instead of npm when trying to build the program. I've also tried deleted node_modules and removing react-navigation from packages.json and even npm install --save react-navigation</p>
