[!] CocoaPods could not find compatible versions for pod "FlipperKit":
  In Podfile:
    FlipperKit (= 0.248.0)

None of your spec sources contain a spec satisfying the dependency: `FlipperKit (= 0.248.0)`.

You have either:
 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
 * mistyped the name or version.
 * not added the source repo that hosts the Podspec to your Podfile.
