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?

Thanks,

there is no more error logs. the whole logs when the app running:

W/ReactNativeJS( 2973): Warning: Native component for "RCTMap" does not exist
W/ReactNativeJS( 2973): Warning: Native component for "RCTModalHostView" does not exist

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 facebook/react-native#4587
