David Angulo cb7f1b1f0b Read `.ruby-version` file in `Gemfile` (#35410) ... Summary: When updating the Ruby version, 2 files are always needed to be updated (`.ruby-version` and `Gemfile`). When not in sync it can lead to an error like `Your Ruby version is 2.7.6, but your Gemfile specified 2.7.5`. This lessens the files that need to be updated when upgrading the Ruby version and makes it in sync always. It makes the `.ruby-version` the source of truth. ### Example 1: <img width="481" alt="Screenshot 2022-11-20 at 13 56 08" src="https://user-images.githubusercontent.com/36528176/202888191-450ab6d0-32a4-4d37-ad82-0beb2b22fa82.png"> When upgrading from `0.70.0` to `0.71.0-rc.0`. 2 files needs to be updated when it could have been just 1. Source: https://react-native-community.github.io/upgrade-helper/?from=0.70.0&to=0.71.0-rc.0 ### Example 2: 21c8837c12 updates 4 files (`.ruby-version`, `Gemfile`, `template/Gemfile`, `template/_ruby-version`) when it could have been just 2. ### Other Sources: * https://andycroll.com/ruby/read-ruby-version-in-your-gemfile/ * https://render.com/docs/ruby-version (Heroku alternative) * https://stackoverflow.com/a/35823132/9375533 ## Changelog [General] [Changed] - Read `.ruby-version` file in `Gemfile` Pull Request resolved: https://github.com/facebook/react-native/pull/35410 Test Plan: Only `.ruby-version` and `template/_ruby-version` needs to be updated when upgrading Ruby version.
