Description

I am trying to make a bare react native project (without expo) and when I try to run my app with the command npm start or npx react-native run-android I get the error: unknown command 'start' or unknown command 'run-android'.

These are the things I have tried:

1. Deleting the node_modules folder and re-installing
2. Making a completely new project
3. The code always warns about punycode depreciation so I tried to mitigate that
4. Converting files into module type from the commonjs type
5. Any other solution mentioned on stackoverflow

Reproducible Demo

You can just create a bare react native project but I think maybe its an issue with my environment or setting so you can download this repository:

Same issue here. Would you know where the start command is for a bare react native project after upgrade to RN 0.76.3?

[liamjones]

The start command should be coming from package @react-native/community-cli-plugin or @react-native-community/cli-plugin-metro. Sorry, I don't know off hand which version RN 0.76 uses.

I got it working after @liamjones shared about this dependency. I went to check and did some debug. After yarn cache clean I did removed the yarn.lock file and run yarn again. It worked. @virajdoshi11 . I also just updated to 0.76.4

[virajdoshi11]

Hi @ribamarsantos & @liamjones , I tried your solution but still not working out for me. It actually doesn't recognize any commands including start and run-android.

Although, after deleting the package-lock.json and running npm install I do see a few errors in the react-native node module. Inside the module in the gradle-plugin folder and all the folders inside it have the error: "Missing Gradle project configuration folder: .settings".

Also when I try any command, I don't know why it first outputs Debugger attached then disconnects and again attaches.

See facebook/react-native#47309

The fix is adding @react-native-community/cli-server-api as a dependency.
