[RUN_EXPO_DOCTOR] This project contains native project folders but also has native configuration properties in app.json, indicating it is configured to use Prebuild. When the android/ios folders are present, EAS Build will not sync the following properties: orientation, icon, userInterfaceStyle, splash, ios, android.
[RUN_EXPO_DOCTOR] ✔ Check that native modules use compatible support package versions for installed Expo SDK
[RUN_EXPO_DOCTOR] The following packages should be updated for best compatibility with the installed expo version:

Error output

[RUN_FASTLANE] ❌  Undefined symbols for architecture arm64
┌─ Symbol: _OBJC_CLASS_$_BLEAdvertiser
└─ Referenced from: in libreact-native-esmart.a[4](MyAppDelegate.o)

[RUN_FASTLANE] 
❌  ld: symbol(s) not found for architecture arm64


[RUN_FASTLANE] 
❌  clang: error: linker command failed with exit code 1 (use -v to see invocation)

This error occures because static library file (.a) is not included in build dir (skipped by .gitignore)

Reproducible demo or steps to reproduce from a blank project

❌ Github Action - eas build --local fails, because .a file ignored (with .gitignore) https://github.com/crutch12/expo-esmart-test/actions/runs/10992514166

✅ And this action works if I remove file from .gitignore https://github.com/crutch12/expo-esmart-test/actions/runs/10992531702

Local builds aim to emulate the behavior of EAS cloud builds. This is just an EAS cloud build process happening on your local machine (with some limitations). As of today it also follows the .gitignore the same way cloud builds do, which is on purpose to make it work very similar to cloud ones to be useful for debugging purposes. We can consider adding a special option ignoring .gitignore in the future, however, I can't promise anything here because our team is currently under a heavy workload. If you want to ignore a different set of files for your EAS build that is excluded by your .gitignore you can use .easignore https://docs.expo.dev/build-reference/easignore/. You can also use npx expo run:[ios|android] to create builds that don't respect the .gitignore file.

Hi, We’re trying to build the project locally but ran into an issue where the .env variables weren't being loaded into the code. All along the problem was that we’re ignoring the .env file in our .gitignore? We don’t want to add our .env file to Git, but then where should we put our API keys and other sensitive data? Thanks!

1. Copy whole .gitignore to .easignore in project's root dir
2. Remove .env from .easignore
3. Done

[!NOTE] Since .easignore fully disables eas's .gitignore files usage: If you have .gitignore files in subfolders and you want eas to skip its ignored files, you should duplicate its content in root .easignore

https://docs.expo.dev/build-reference/easignore/ By default, the EAS CLI refers to the .gitignore file (if it exists) to determine which files to ignore. If you create a .easignore file, the EAS CLI prioritizes it over the .gitignore file. When creating a .easignore file, include all files and directories from your .gitignore file and add additional files you want to ignore.

Thanks, I will test it next week. Regards!

I had the same issue, @crutch12 solution works, I think it would be useful if when using --local, gitignore would be ignored.

This issue is stale because it has been open for 30 days with no activity. If there is no activity in the next 7 days, the issue will be closed.
