You may have installed it by accident. Try npx react-native@0.63 init or npx @react-native-community/cli init which will also work.

@jgcmarins @DevHabit it’s apparent you have a globale react-native binary installed, (react-native-cli module), which you should remove. Please make sure to run npm uninstall -g remove react-native react-native-cli and same for Yarn. Check some older Node versions or caches. Running which react-native shouldn’t return anything. Then you can run:

npx react-native init MyAwesomeApp --template react-native-template-typescript

as official RN docs advise: https://reactnative.dev/docs/typescript
