Answer 1

_uninstall everything you have installed expo react-native and node (_uninstall您已安装expo react-native和node的所有内容)

_install Node@V10.xx (_install Node@V10.xx)

_install react-native or expo and enjoy (_install react-native或expo并享受)

in most cases nodejs on version 12 causes many error for react-native and the most stable version is 10.xx (在大多数情况下，版本12上的nodejs会导致react-native出现许多错误，而最稳定的版本是10.xx)

try this and let me understand you're problem is solved. (试试这个，让我明白您的问题已经解决。)
