title: npm start not working for react native setup
body: <p>Hei,
  I'm new to programming and trying to Setup my toolchain and create a new React Native project.</p>
  <ul>
  <li>If needed, install code editor (+ extensions), git, npm</li>
  <li>Install the Expo app to your phone. iOS or Android</li>
  <li>Use the expo CLI tool to generate an app skeleton</li>
  <li>Create a folder for your React Native projects</li>
  <li>use Git Bash or terminal to go to this folder cd foldername/otherfoldername/etc...</li>
  <li>npm install -g expo-cli</li>
  <li>expo init MyApp --npm</li>
  <li>choose 'blank' template</li>
  <li>if this fails on Windows due to missing interactive mode, use cmd instead of Git Bash
  Test that app works; run it and open in the browser (the interactive shell is needed to get the menu option (w) for launching in browser)</li>
  <li>cd MyApp</li>
  <li>npm start &lt;---</li>
  <li>From now on open 'MyApp' folder in your editor/IDE to edit your project
  Create a remote git repository (Github) and push your app there</li>
  </ul>
  <p>I have done these but I get this error when I write in my VScode npm run</p>
  <ul>
  <li><p>expo start</p>
