Problem with installing native part of react-native-reanimated

[ghost]

We have a custom build project. I've anonymized the absolute path to the project and the name, and left out some more irrelevant folders.

<project>
|- app
  |- Pods/
  |- Podfile
  |- Podfile.lock
  |- _.xcodeproj/
  |- _.xcworkspace/
|- webclient
  |- package.json
  |- node_modules/
  |- src/
    |- web (web app code)
    |- native (react native code)

Steps:

1. I installed the package react-native-reanimated
2. Updated my babel config
3. Ran pod install. This is the error I get:

Analyzing dependencies
node:internal/modules/cjs/loader:1078
  throw err;
  ^

}

Would really appreciate any debugging help here! Thank you!

Hey @tanishqk-shortwave, because you have custom setup, Reanimated is not able to properly detect path to React Native sources. As a workaround, you can hardcode the paths in reanimated_utils.rb so it works with the structure of your project and apply the patch using patch-package.
