title: React Native Error: ENOENT: no such file or directory
body: <p>I am building a react native app without expo and am running into an error when running the command "react-native run-ios". Metro bundler reports an ENOENT error since the bundler is seemingly looking in a directory one level up from the projects root directory and therefore can not find the necessary modules. </p>
  
  <p>I have already tried restarting the bundler, my computer, the ios simulator, and updated packages</p>
  
  <p>Here is the specific error message after running  "react ntive run ios"</p>

  <p>I have previously been able to build a project and this new issue popped up after adding the firebase sdk to the project. I have seen other ENOENT errors but none seem to deal with a packager searching in the wrong directory for files.</p>
