Unexpected token import, v0.56.0-rc cliEntry.js error

Using the latest RN pr v0.56.0-rc When running ‘react-native run-android’, I get an error saying it doesn’t recognize the import command in clipEntry.js, line 30.

...\node_modules\react-native\local-cli\cliEntry.js:30
import type { CommandT } from './commands';
^^^^^^

@hramos Please re-open this issue. Although the template is not provided, this is a major blocking issue for any react-native development on Windows, including react-native-windows apps.

This seems to be an issue with how babel 7 resolves paths on windows. There is some path seperator replacement in https://github.com/facebook/metro/blob/master/packages/metro-babel-register/src/babel-register.js. If you remove both occurences of .replace(/\\/g, '/') the cliEntry error is gone. However, there seems to be an issue with haste module resolving on windows then.

Might be a react-native issue, might be a metro issue or might be a babel issue. Anyways, v0.56.0-rc is broken on windows.
