title: DIfferences between create-react-app on macos vs linux?
body: <p>I'm getting a weird error from a project that I started from create-react-app on a macbook. When I cloned the project on my ubuntu drive, when I launch the app (npm start), it gives me this error. With some node &amp; express errors.</p>
  
  <pre><code>TypeError: Path must be a string. Received undefined
  at assertPath (path.js:28:11)
  at Object.join (path.js:1236:7)
  </code></pre>
  
  <p>I tried reinstalling my dependencies, clearing npm cache, even reinstalling node.
  I noticed some dependencies wouldn't work on linux.
  The weird thing is, I have started other react projects on my linux machine and it works fine. The only one that gives me cryptic errors is the one I originally made on macos. Any clues as to what it could be ? </p>
