Currently, starting a new project throws the error "Error: Invalid sdkVersion."

Description

Following the instructions in the read.me gives the error “Invalid sdkVersion”

Expected Behavior

If someone is following instructions from the readme shouldn’t it work?

Observed Behavior

I had to change the sdkversion of expo and react-native. I also had to clear the watchman cache and delete node_modules and reinstall packages. This could have been avoided if the sdk version was set to version that worked.

Error: Invalid sdkVersion. Valid options are 10.0.0, 11.0.0, 12.0.0, 13.0.0, 14.0.0, 15.0.0, 16.0.0, 17.0.0, 18.0.0, 19.0.0, 20.0.0, 21.0.0, 22.0.0, 23.0.0, 24.0.0, 25.0.0, 7.0.0, 8.0.0, 9.0.0

Environment

Please run these commands in the project folder and fill in their results:

• npm ls react-native-scripts: 1.13.1
• npm ls react-native: 0.54.0
• npm ls expo: 26.0.0
• node -v: 9.8.0
• npm -v: 5.6.0
• yarn --version: 1.5.1
• watchman version: 4.9.0

Also specify:

1. Operating system: Mac high sierra 10.13
2. Phone/emulator/simulator & version: iOS sim v10

Changing expo to v25 and react-native to v52 fixed this error. Just wondering why it’s set to an unsupported sdk version.

Reproducible Demo

Just follow the readme. create-react-native-app my-app cd my-app npm run start

Mine is 50.0.5

Going to update and see if that resolves the issue.

Doing that in addition to also reseting and reinstalling the expo app on the ios sim made it work. Thanks for the quick reply.
