[!] CocoaPods could not find compatible versions for pod "XXXX":
XXXX (= 126.96.36.199416113435)
None of your spec sources contain a spec satisfying the dependency: `XXXX (= 188.8.131.52416113435)`.
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* out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.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.
Note: as of CocoaPods 1.0, `pod repo update` does not happen on `pod install` by default.
pod install --repo-update
The sandbox is not in sync with the Podfile.lock. Run ‘pod install’ or update your CocoaPods installation.
