I am a beginner in react-native and I can not make a pod install in my iOS project. Thank you in advance.

Answer 1

Most of the times this happens when you have more then one Xcode development version. Well thats what happened to me. You can try re-configuring/changing the xcode-select path to default Xcode.app:

Check your Xcode app name first

xcode-select -p

If its not Xcode.app then do this:

sudo xcode-select --switch /Applications/Xcode.app

after that run pod install again

If its already set to Xcode.app then try following:

cd node_modules/react-native/third-party/glog-* ../../scripts/ios-configure-glog.sh

i didn't need to do that because the step before worked already, maybe it helps you :)

I'm promoting Chase Holland's comment to an answer, because it solved my problem: remove any spaces you may have in your Xcode path.

/Applications/Xcode 10.0.app: will cause the error above

/Applications/Xcode10.0.app: will not
