title: Npm start gives me : 'react-scripts' is not recognized as an internal or external command, operable program or batch file.'
body: <p>Here's my remote repo, I made the project with 'create-react-app':
  <a href="https://github.com/mattfrancis888/project_2" rel="noreferrer">https://github.com/mattfrancis888/project_2</a></p>
  
  <p>Whenever I clone the project and try to launch it with npm start. It gives me: </p>
  
  <p>'react-scripts' is not recognized as an internal or external command,
  operable program or batch file.'</p>
  
  <p>Why is that? I tried:</p>
  
  <ul>
  <li><p>doing 'npm i' </p></li>
  <li><p>npm install react-scripts --save (<a href="https://stackoverflow.com/questions/47928735/react-scripts-is-not-recognized-as-an-internal-or-external-command">&#39;react-scripts&#39; is not recognized as an internal or external command</a>)</p></li>
  <li><p>deleting and cloning the project again.</p></li>
  </ul>
  
  <p>The project  works in my other computer (the desktop where I made the remote repo)</p>
