title: No podspec found for `React-Core` in `../node_modules/react-native/React`
body: <p>I'm using React Native. I get this issue when I try to upload pods. I've successfully installed node_modules, but I'm getting this problem. What is the problem? If we delete the package-lock.json and node_modules folder, I reinstalled npm. But I'm having this problem when I'm doing pod install.</p>
