hi, since the maintainer is not maintainig this library anymore and is not releasing it so you're getting the current version via npm (see https://github.com/javascript-obfuscator/react-native-obfuscating-transformer/issues/27) you have to checkout the repo yourself and build it via "npm run build".

I've got it running with current RN (0.64) by upgrading dependencies + some necessary code changes -> see https://github.com/javascript-obfuscator/react-native-obfuscating-transformer/pull/45/commits/10fe3ec28ca8d68a4a2cc4e0455b10f0c08eca26 and/or just checkout my forked repo, build and overwrite the resources from your node_modules.

I hope that helps. Alternatively you can use javascript-obfuscator directly as mentioned in https://github.com/javascript-obfuscator/react-native-obfuscating-transformer/pull/15.
