Can't find variable: Symbol

[atom992]

Hi, my env: react-native-cli : 0.1.7 react-native : 0.16.0 react-native-icons: 0.7.0
when I run my app ,I got the following error: E/ReactNativeJS( 2973): Can't find variable: Symbol
but the Example of react-native-icons works fine.

Can you share more of the error or logs? Like where that error is happening?

Maybe try a clean and rebuild and make sure you've restarted the packager after upgrading RN or this library as well

This doesn't appear to be an issue with this module. See https://github.com/facebook/react-native/issues/4587
