see: https://blog.expo.dev/expo-sdk-46-c2a1655f63f7

you should run npx expo start starting with sdk 46, rather using the globally installed expo-cli

let me know if this issue persists after you have done that

You can skip this check with the environment variable EXPO_NO_TYPESCRIPT_SETUP=1.

It's still not working, and now, I can't run my project. @brentvatne

@EvanBacon I put inside my .zshrc file the environment variable but it didn't work.

[brentvatne]

you need to use export - like with the other env vars above that. also, EXPO_USE_LOCAL_CLI=1 isn't needed on sdk 46+, it is the default

hey @ildaneta, did you reolve this isssue, I'm also facing the same after upgrading a project from sdk 44 to sdk 46.

[ildaneta]

Thank you so much @brentvatne

Hi @jarapamikaella!

So, with the line above inserted in my zshrc file, resolved my problem! export EXPO_NO_TYPESCRIPT_SETUP=1
