if you are having problems in creating your first native react app using this
line of code
"npx create-react-app" and even with this
"npx react-native init Examiner" and you encounter this error
"cli error not function",
uninstall the cli.
and if you use this line of code
"npx react-native init Examiner" and met
another error
there is a simple solution
use
"npx @react-native-community/cli init Examinerr"
then find the folder and start the app
this should create your first App as easy as Pie.
