1- Something is Missings
There is missing index.js file which is mendatory for npm packge. you can see in screenshot

-
2- You need to perform these steps to resolve this package
Step 1:
make index.js file at node_modules/react-native-jitsi-meet/index.js
Step 2:
and this add code in that index.js file
import { NativeModules, requireNativeComponent } from 'react-native';
export const JitsiMeetView = requireNativeComponent('RNJitsiMeetView');
export const JitsiMeetModule = NativeModules.RNJitsiMeetView;
const call = JitsiMeetModule.call;
const audioCall = JitsiMeetModule.audioCall;
JitsiMeetModule.call = (url, userInfo) => {
userInfo = userInfo || {};
call(url, userInfo);
}
JitsiMeetModule.audioCall = (url, userInfo) => {
userInfo = userInfo || {};
audioCall(url, userInfo);
}
export default JitsiMeetModule;

after these steps everything will be working
Node: you should automate these steps when we install any package by npm
or yarn
we can use patch-package to automate these steps
