CocoaPods stopped installing Firebase/Analytics with error

问题

I've installed Firebase/Analytics into an iOS Project yesterday (as I've done many times before) and today I wanted to add Firebase/Crashlytics and suddenly both of them don't work anymore.

I get the following error message:

[!] CocoaPods could not find compatible versions for pod "Firebase/Crashlytics": In Podfile: Firebase/Crashlytics (= 4.0.0)

There are other pods (e.g. GoogleMaps, Resolver, Alamofire, etc) which work fine. Just the Firebase/* stuff doesn't work.

If I remove the / and try to install FirebaseAnalytics and FirebaseCrashlytics it works (the pod install does at least) but then xCode tells me it cannot find the Firebase module.

Here is my pod env

xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance

target 'project' do
  # any project specific pods

I'm at a bit of a loss here and any hints would be greatly appreciated.

回答1:

Remove the slashes from Firebase/Crashlytics and Firebase/Analytics.

The slash indicates a subspec of the Firebase pod.

You could also leave the slash and specify the version of the last Firebase pod - 6.23.0.

回答2:

It's because of version conflict.

use pod 'Firebase/Crashlytics' with slash and without version. (or newest version)

and run pod update Firebase/Crashlytics Firebase/Analytics

if you have other version conflict, run pod update Firebase/Crashlytics Firebase/Analytics GoogleXXX(s)
