I am using react-native-webrtc in my expo project. but when I try to run it using ‘npm expo start’ and try to see it in expo go, it says:  
ERROR Error: WebRTC native module not found.  
Try executing the “npm install” command inside your projects folder., js engine: hermes  
ERROR Invariant Violation: “main” has not been registered. This can happen if:

- Metro (the local dev server) is run from the wrong folder. Check if Metro is running, stop it and restart it in the current project.
- A module failed to load due to an error and `AppRegistry.registerComponent` wasn’t called., js engine: hermes

Can u help me

You need to compile a development build.  
You wont be able to use expo go anymore.
