Pod install does not work with my react-native app

Question

I'm trying to build an app on ios in react native using eas build.

Things goes well except wen it comes to do pod install in the IOS directory. I got this error :

pod exited with non-zero code: 1

And this is my Podfile :

I'm on expo 44. And my pod version is 1.12.1 on Mac M1. Cacaopods 1.12.1 and ruby 2.6.10

Any ideas ?

Thanks

I've found nothing on google with this type of error for mobile app. So I'm asking here.

Answer 1

To fix this issue, I was using an old version of Ruby, so I downloaded a newer version; I was using Ruby 2.6.10, whereas passing it to 3.0.0 solved it.

And for the bad URI on Folly, I changed it with this line:

pod 'RCT-Folly', :podspec => '../node_modules/react-native/third-party-podspecs/RCT-Folly.podspec'

I don't know why—maybe when I've upgrade the project from Expo 39 to Expo 44?—the Folly.podspec disappeared and was replaced with RTC-Folly.podspec.

Answer 2

Are you on M1? If you are you can try running:

arch -x86_64 pod install
sudo arch -x86_64 gem install ffi

If you are not, probably pods are already installed so you can try with pod update or removing ios/build and ios/Pods, then pod install again.
