title: CocoaPods could not find compatible versions for pod "React/Core"
body: <p>when I start pod install
  the result :</p>
  <p>[!] CocoaPods could not find compatible versions for pod &quot;React/Core&quot;:
  In Podfile:
  react-native-fetch-blob (from <code>../node_modules/react-native-fetch-blob</code>) was resolved to 0.10.6, which depends on
  React/Core</p>
  <p>None of your spec sources contain a spec satisfying the dependency: <code>React/Core</code>.</p>
  <p>You have either:</p>
  <ul>
  <li>mistyped the name or version.</li>
  <li>not added the source repo that hosts the Podspec to your Podfile.</li>
  </ul>
  <p>I try to fix like
  pod repo update* + pod update
  remove podfile.lock
  still not working
  thanks advance
