bug: missing module @babel/runtime

[losh11]

I've added react-native-lightning to my app, and when building with Xcode, it fails with error:

warning: the transform cache was reset.
                    Welcome to Metro!
              Fast - Scalable - Integrated


error Unable to resolve module @babel/runtime/helpers/interopRequireDefault from /Users/loshan/Repos/react-native-lightning/dist/index.js: @babel/runtime/helpers/interopRequireDefault could not be found within the project or in these directories:
  ../react-native-lightning
  ../react-native-lightning/node_modules

If you are sure the module exists, try these steps:
 1. Clear watchman watches: watchman watch-del-all
 2. Delete node_modules and run yarn install
 3. Reset Metro's cache: yarn start --reset-cache
 4. Remove the cache: rm -rf /tmp/metro-*

Fix is to 'yarn add @babel/runtime` and merge to this library.
