Unable to resolve module 'tslib'

Unable to resolve module `tslib` from `/Users/TestUser/TestProject/node_modules/react-native-notifications/lib/dist/index.js`: Module `tslib` does not exist in the Haste module map

This might be related to https://github.com/facebook/react-native/issues/4968
To resolve try the following:
  1. Clear watchman watches: `watchman watch-del-all`.
  2. Delete the `node_modules` folder: `rm -rf node_modules && npm install`.
  3. Reset Metro Bundler cache: `rm -rf /tmp/metro-bundler-cache-*` or `npm start -- --reset-cache`.
  4. Remove haste cache: `rm -rf /tmp/haste-map-react-native-packager-*`.

I get this redbox issue when trying to run the project. I know a workaround is to add tslib as a dependency into my project’s package.json.

However, I don’t think that is very clean.

What is the optimal way to remove this issue from this great project?

Is this really the solution? Why isn’t the library installing it as a dependency?

yarn add tslib solved this for me
