Module not found: Package path . is not exported from package /home/naveen/New Folder/whatsapp-2/node_modules/firebase (see exports field in /home/naveen/New Folder/whatsapp-2/node_modules/firebase/package.json)
Did you mean './firebase'?
Requests that should resolve in the current directory need to start with './'.
Requests that start with a name are treated as module requests and resolve within module directories (node_modules).
If changing the source code is not an option there is also a resolve options called 'preferRelative' which tries to resolve these kind of requests in the current directory too.
