Steps to reproduce

npx react-native init testPodInstall
cd testPodInstall
bundle install
cd ios; bundle exec pod install; cd ..
# Change react-native version from "0.71.6" to "0.71.5" in package.json
yarn install
bundle exec pod install --project-directory ios
# or
npx pod-install

Result ios/Podfil.lock

  - hermes-engine (0.71.6): // <--- Ops... HAVE TO BE "0.71.5"
    - hermes-engine/Pre-built (= 0.71.6)
  - hermes-engine/Pre-built (0.71.6)

This feels like a bug that we want to investigate on. cc @cipolleschi

Came here to say the same. This is problematic in CI.

Updating from 0.71.6 to 0.71.7 here's what we did:

yarn upgrade react-native@0.71.7 --exact
npx pod-install

...no mention of hermes-engine

Then in CI we have a couple steps before a Fastlane build:

    - cd ios
    - gem install bundler
    - bundle install
    - gem install cocoapods
    - pod install --repo-update

Yet this error occurs:

 CocoaPods could not find compatible versions for pod "hermes-engine":
  In snapshot (Podfile.lock):
    hermes-engine (from `../node_modules/react-native/sdks/hermes-engine/hermes-engine.podspec`)
  In Podfile:
    hermes-engine (from `../node_modules/react-native/sdks/hermes-engine/hermes-engine.podspec`)
It seems like you've changed the version of the dependency `hermes-engine` and it differs from the version stored in `Pods/Local Podspecs`.
You should run `pod update hermes-engine --no-repo-update` to apply changes made locally.

To resolve, we had to run pod update hermes-engine --no-repo-update locally and then push the Podfile.lock changes

Hi @jforaker, thanks for posting this.

A quick question to understand better: when you run

yarn upgrade react-native@0.71.7 --exact
npx pod-install

Was the app working? did this update the Podfile.lock?

Because, if that's the case, perhaps you missed to update the Podfile.lock.

Also, I see that you install bundler, but you are running all the commands without bundle exec, which, basically, is ignoring bundler completely. Is this done on purpose?

Yes it was working. Everything except the Hermes portion got updated in Podfile.lock

@cipolleschi - not on purpose, I will revisit my CI steps as it’s been a long time since that was written.

Hi there, Sorry for the late answer.

Yes it was working. Everything except the Hermes portion got updated in Podfile.lock

Well, then it means that pod install is actually updating Hermes and that the Podfile.lock should be pushed to CI, no?
Isn't that expected that CI will fail if there is a file that is outdated? 🤔

Hi, I can confirm this issue when upgrading from 0.71.2 to 0.71.7.
After upgrading with react-native upgrade, the build locally succeeds, with the Pod lockfile still showing hermes-engine 0.71.2.
Building in CI pipeline without installed dependencies then fails.
deleting Gemfile.lock and Podfile. lock as well as the pods and vendors folder, then running:
bundle install -> bundle exec pod install
updated the hermes pod to 0.71.7 in the lock file successfully.

Kind Regards

@cipolleschi when run pod install --project-directory ios or npx pod-install after RN version changing
it's updating all RN related pods except Hermes engine :(

and when I do cd ios; pod install; on CI or locally it fail with the next error:

 CocoaPods could not find compatible versions for pod "hermes-engine":
  In snapshot (Podfile.lock):
    hermes-engine (from `../node_modules/react-native/sdks/hermes-engine/hermes-engine.podspec`)
  In Podfile:

It seems like you've changed the version of the dependency `hermes-engine` and it differs from the version stored in `Pods/Local Podspecs`.
You should run `pod update hermes-engine --no-repo-update` to apply changes made locally.

and when you check Podfile.lock

  - FBReactNativeSpec (0.71.6): // the same that I have in package.json !!!
  - hermes-engine (0.71.5) // <-- OLD VERSION
