title: No podspec found for `React-Core` in `../node_modules/React`
body: <p>First its not duplicated. Because i have different issue. I upgraded my react Native version to '0.62.2' (I wish I hadn't upgraded). I'm dealing with a lot of problems right now.This is my problem now  No podspec found for <code>React-Core</code> in <code>../node_modules/React</code> and I couldn't solve it</p>
  <p>It is seen that there is always wrong path in similar problems. But even though I wrote the correct path, it gives an error. Also when I look at '../node_modules/react-native' I can't see the React-Core file here
