CocoaPods could not find compatible versions for pod “GoogleDataTransportCCTSupport”

问题

I've installed Firebase In App Messaging according to the guide: https://rnfirebase.io/in-app-messaging/usage

When I run pod install, I get this:

Using firebase.json from '/../app/firebase.json'

You have either:
 * changed the constraints of dependency `GoogleDataTransportCCTSupport` inside your development pod `RNFBInAppMessaging`.
   You should run `pod update GoogleDataTransportCCTSupport` to apply changes you've made.

I've tried a few things including pod install --repo-update but nothing helps.

回答1:

Adding pod 'FirebaseCoreDiagnostics', '1.2.1' to the Podfile might be a workaround since that podspec only needs GoogleDataTransportCCTSupport 1.x.

Those Firebase versions are several months old - so another approach would be to encourage React Native to update the wrappers.
