Unable to find a specification for `ExpoModulesCore` depended upon by `EXApplication`

In my case I faced this error when integrating Expo Modules to a Bare RN 0.67.2 Project. However, the project is a monorepo with multiple targets in the Podfile. This custom structure meant the auto patch failed.

I added this snippet (from the setup guide) to the very end and everything works now.

use_expo_modules!

post_integrate do |installer|
  begin
    expo_patch_react_imports!(installer)
  rescue => e
    Pod::UI.warn e
  end
end

EDIT: some findings / background - for my use case is desire to simply use expo-web-browser and get an app with 4 tabs. It seemed like I could simply start up the expo project and quickly eject. This I believe is what the expokit sdk was for - which is deprecated/obsolete. Ejecting seems like a road to horror / or at least unfavourable to get things working. To get around this problem - seems like best to start a new expo project - import/ cherry pick across all the code - and avoid run expo eject. I’m fine with that - it should be noted that running expo run:ios (automatically runs eject) as opposed to yarn run ios which keeps you inside expo. The fixes below are likely to be out of date come sdk 45.

RANDOM RAMBLINGS - TROUBLESHOOTING I’m running node 14 and seeing same problem - if that helps. going to bump to later version.

 npm i -g npm@latest

RUBY -  ruby-2.7.4
expo-cli --version
5.2.0

pod --version
1.11.2
NVM -   v16.14.0

react-native-cli: 2.0.1
expo --version

rm -rf node_modules
yarn upgrade --latest

# will downgrade react from 
cd ios
rm -rf Pods
rm Podfile
pod install --repo-update

still no joy.

this is my package.json https://gist.github.com/pe-johndpope/74d330f531d2fed95c997a14a264cb38

UPDATE - still no joy… I’m seeing this with sdk 43…

PARTIALLY WORKING

expo install expo@42.0.5
expo install  react-native@0.63.4
expo doctor --fix-dependencies 

package.json -> “expo”: “42.0.0”, app.json -> “sdkVersion”: “42.0.0”

downgrading to 42 works for now. Need to remove Podfile react_native_post_install

UPDATE - FIX you’re gonna need to overhaul your podfile with extra things here’s a comparison to my broken file. https://gist.github.com/pe-johndpope/e34987568454dd3b4b3fc8104122414b
