I am getting this error every time I start up my Expo server. This app is using React Native and Realm (the issues started when I installed Realm). I have run Pod Install several times, without success. The full error messages I am getting are:
WARN Constants.platform.ios.model has been deprecated in favor of expo-device's Device.modelName property. This API will be removed in SDK 45. ERROR Error: Missing Realm constructor. Did you run "pod install"? Please see https://docs.mongodb.com/realm/sdk/react-native/install/ for troubleshooting, js engine: hermes ERROR Invariant Violation: "main" has not been registered. This can happen if:
- Metro (the local dev server) is run from the wrong folder. Check if Metro is running, stop it and restart it in the current project.
- A module failed to load due to an error and
AppRegistry.registerComponentwasn't called., js engine: hermes.
The issue is specifically occurring for iOS.
After reading several other Stack Overflow and Github posts, I tried the following, without success:
- Installing Hermes
- Reinstalling Node, NVM, and NPM
- Running "Pod Install"
- Downgrading and Upgrading the version of React Native
- Uninstalling and reinstalling Node Module and package-lock.json
- Modifying my index.js file to register component main.
None of these resolved the error - I have consistently received the same error messages when building my iOS bundle.
