How do I resolve "Could not locate Gemfile" when trying to initialise a react native project?

Question

When running the command npx react-native init myProject --version 0.63.0 it gives back the error:

✖ Installing Bundler
error Could not locate Gemfile

I am using react-native 0.63 as I am on Mac OS 10.13.6. Xcode 12 is required for react-native 0.64, which I can't get on this old OS (please don't suggest to upgrade it's not a feasible solution). I understand the error is caused by a Gemfile not existing in the project directory, but how can I resolve this?

I have followed the installation steps as per https://reactnative.dev/docs/0.63/environment-setup.

Here is the output when I run cd myProject && gem env
