Had the same issue and after restarting my computer the issue went away for me. You might have to just close and restart your terminal and simulator too.

I've just found a workaround:

yarn remove babel-preset-react-native
yarn add babel-preset-react-native@2.1.0

The hole is probably deeper, but that is works for me.

I've tried to create a new RN app by RNCA (Expo) and then eject it. Works perfectly fine, although it runs on React Native 0.46.1, so I'm guessing this is an issue with 0.47.

Thank you for reporting and for the workaround @esganzerla.

It seems an issue with babel-preset-react-native@3.0.0 that was released earlier.

@jeanlauliac How should we fix this issue? Add a specific major version in react-native-cli? Or something has been planned?

react-native/local-cli/init/init.js

Line 91 in a54d449

`jest babel-jest babel-preset-react-native react-test-renderer@${reactVersion}`

cc @ericnakagawa who's on call.
