37.0.0 is not a valid SDK version

Dear All,

I just use expo init projectname to create a new project and nothing to add or edit, then I try to run npm start and run emulator in windows 10 environment.
the emulator is shown the error …
37.0.0 is not a valid SDK version.

but if I run my old project which the SDK is 36.0.0, then is ok no problem.

please help how can I solve this problem

1.npm i -g expo-cli
2. close all your emulators
3. expo client:install:android (or ios)
4. expo start -c


try updating the app


hey there! you may have an old version of the client cached due to an intermittent issue we had with deployment. to fix this:

  1. delete the apk cache

on macos: delete the ~/.expo/android-apk-cache directory
on windows: same thing, find and delete the .expo/android-apk-cache directory (maybe in C:/Users/YourUser/)

  1. run expo client:install:android

Just update the Expo app on your phone. Fixed the issue for me. :slight_smile:
