Looking at the original docs, I ran npx react-native init AwesomeProject and didn't change anything.

I get attachToServer is not a function error when I run npx react-native start or yarn start. Both don't work. I didn't have this issue before I don't know what might be causing it. Using expo I can start metro so this is probably react-native cli issue.

Here are the package versions.
